    I've never been brave enough to work on a household ac system aside from changing capacitors and cleaning corrosion. This winter though, the electric furnace went out and I got a crash course in how they function due to necessity. It turned out to be a combination of a failing sequencer and a failing thermostat. Tricky to track down when you're learning!

    • @stuzman52
      @stuzman52  6 років тому

      John Lane we all start out John in knowing nothing. But as time passes we learn new and different things. I always look to learn something new as it keeps life interesting. And good of you to continue in your quest for knowledge. The case in point of you learning about the electrical heating system in your furnace. 😀👍

    • @johnmichaellane1
      @johnmichaellane1 6 років тому

    Ours was fine last night. This morning it was not as cold as normal.
    Outside fan running blowing ambient (not hot) air. Inside unit running fine.
    Cleaned evaporator & condensing coils. Changed filter (New one 5 days ago). Cleaned drain line in case clogged.
    I'm thinking capacitor - as I said outside fan running but no deep 'hum' of compressor running.
    Note: or system is from late 1990s 🤣 (94 to be exact). We rent and don't see new system any way possible so I guess another band-aid repair it is!

    • @stuzman52

    Hope you can answer a question for me. Our central ac went out two days ago. I watched a ton of videos and came to the conclusion my capacitor needed to be changed. I could push the plunger in and the compressor and fan would kick on but the blower in the house wouldn't come on. I just put the new capacitor on but it's the same thing. I just put a new thermostat on a few months ago and it has been working fine. Like the most of the country, we here in SW Missouri have been going through a heat wave. Yesterday the heat index was 102 and it got up to 89 in the house. My wife and I are both on social security so I am trying to find the least expensive way to get this done myself. Any ideas you may have would be greatly appreciated. Thanks!!

    • @stuzman52

      Hi Wm and sorry to hear that you're going through this heat wave. Take a look at the motor inside the air handler and find the voltage source going to the motor. That would be the first thing to check. You said that you changed the capacitor. I'm assuming that you're talking about the capacitor for the indoor fan unit. If so, then be sure to check the voltage going to the motor. If that's okay, then most likely you have an issue with the motor that needs replacing. Let me know how it goes so you and your wife can get back up and running.

      @@stuzman52 Hey, thanks for the response. No, the capacitor that I changed is the one on the outside unit. I figured the blower motor should be okay because I run it on manual to keep a bit of an air flow in the house. After I changed the capacitor outside, I pushed in the plunger contact and the outside unit would come on (compressor and fan) but the blower on the furnace doesn't kick on. So when I run the furnace blower, is that bypassing the capacitor for the blower? Someone told me it could also be low on refrigerant. I really don't think that is the case however because when it was working, it was blowing very cold air. The electrical panel on the outside unit is so hard to get to. On the left side is steps going up on the deck, on the backside is the deck and on the right side is the wall to the house, so I literally have to lay on the unit and work upside down. LOL I guess I'll try to do some more testing and see if the low voltage from the thermostat is ok on the plunger contactor and the voltage on the furnace motor. Like I stated, I don't know if when I run the blower on manual if it is bypassing the blower motor's capacitor. Any advice would be greatly appreciated. My wife and I are both 67 and on Social Security and just trying to get by. Thank you so much!!

      @stuzman52  3 роки тому

      @@CombatDoc54 Okay, Wm. The capacitor inside the outside unit has nothing to do with the blower motor inside. The capacitor that's outside is a dual capacitor where one is used to start the compressor and the other capacitor is to start the condenser fan. You need to take a look at the wiring diagram on the inside cover of the outside unit and see why the contactor in the outside unit is not energizing. One of these components for energizing the contactor is the thermostat. You need to look at the wiring diagram for the control side of the contactor, (the coil) and see why it's not getting 24VAC. There could be pressure switches located in this circuit which are for low and/or high pressure switches for the refrigerant. That's where I would start for your troubleshooting. Good luck Wm!

    Have a question? 2 wks ago I had HVAC here checking my ac. The refrigerant was ok. The issue was the compressor would kick on, the lines would get cool like they're supposed too and then shut off within 20-30 seconds. The HVAC guy replaced the run capacitor but the compressor still wouldn't stay running. It would start, run and then shut off. The guys couldn't figure out the problem and left. My ac unit is a 1979 rheem with the original 1979 Copeland compressor if that helps. Everything else on the ac unit and inside works as far as I was told.

    • @stuzman52
      @stuzman52  3 роки тому +2

      When the compressor just drops out and the outside fan still works according to your description, would put the problem in the compressor circuit. Most likely, there is a loose connection. Look at the wiring diagram and check all the connections that include the start, run and common wires at both ends, connections on the run capacitor for the compressor. And you want to especially check the connections directly at the compressor. If you don't find any loose connections, then I would suspect that there is an internal opening of one of the windings inside the compressor. To confirm this, when the compressor shuts down, you'll want to check for continuity between the common, run and start windings of the compressor. You should be able to do this inside the control panel of the outside unit. And you'll want to do this quickly as the compressor cools, the winding may 'heal'.

    Thank you for sharing this knowledge. I have this problem, but when I flip the breakers on the unit and main breaker box (they didn't trip), it comes back on about 50% of the time (repeat process if it doesn't). Only does it when cooling and typically when there is a lot of demand for cooling (very hot outside). I doubt the winding are bad on the compressor. I've also checked for iced cooling coils, but no. The drain is also free/not a full pan with a float switch (it pipes to a sump pump). The fan/blower keeps going fine, but the compressor stops seemingly at random. The thermostat is also new/no reason I would be suspect of it. Someone said the compressor breaker on the unit (box surrounding the blower/ducting) could be slightly off/crooked and seated wrong, which would explain why flipping it fixes the issue at random. Does that seem plausible? I don't necessarily expect an easy answer, although that would be awesome, just any kind of push in the right direction would be awesome.

      Ian, it sounds like you're missing either the 24VAC control voltage to the contactor coil inside the outside unit or you're missing a leg possibly on the 240VAC that's feeding the outside unit. I would take the electrical cover off the outside unit and when you can get the issue to happen, check that the contactor is pulled in. You can look at the contactor visually or better yet, check the voltage to the coil and verify that its 24VAC. If that's good, then check from L1 to ground. You should have 120VAC. Check from L2 to ground. You should have 120VAC. Check from L1 to L2. You should have 240VAC. Of course L1 and L2 are the line power wires being fed from the disconnect into the outside unit and will go to one side of the contactor. Let me know what you find.

    I'm having an issue I believe to be the vacuum or compressor pump. My unit will still be running but it will stop blowing cold air. To fix the problem I've been turning the thermostat on and off, sometimes it takes 2-3 tries. I've noticed that I can hear a loud hum when it's working properly, but that hum is gone when it's not. And I can also see liquid moving in the sight glass when it's working, but no liquid moving when it's not. Sounds like a pump to me because everything else is working fine. The pump does start eventually but it will stop working before reaching temp, and then the unit continues to run without cold air. What do you think?

    • @stuzman52
      @stuzman52  2 роки тому

      It could be a faulty thermostat, but you'll need to do a little detective work to confirm. When the unit is acting up, take the control panel off to expose the line contactor inside the outdoor coil unit. Place a voltmeter across the coil terminals of the contactor and if you don't see 24VAC, then the most likely cause is a faulty thermostat.

    • @stuzman52
      @stuzman52  2 роки тому

      @@excuseme4960 Okay, by having 24V across the contactor coil there isn't a problem with the thermostat. And since you have 240V across both sides of the contactor, the contactor is good. The next time the contactor starts, verify that you hear the compressor start. If it starts, but there is a humming sound, then it's a good chance that the run capacitor is defective. To check, turn off the power to the outdoor unit. Bridge across the terminals of the run capacitor to discharge any residual charge that may be left on the cap. Remove the wires taking note of where each one goes on the terminals. Using a DVOM which if it's a good one will have a function to check the capacitance. You will see three terminals marked C, (common), Fan, and Herm (Hermetic which is for the compressor). Check between the C and Fan for its capacitance, and check between C and Herm for its capacitance. It should be +/-10% from the value on the capacitor. If not, replace the capacitor. Let me know what you find in these steps.

The problem I have with my compressor is that it will not restart after it has run low of air. It will start from the beginning with no air in the tank and build up to the required pressure. But once the air as depleted down to a lower level it struggles to restart. It just turns over slowly and does not restart. If the air is completely emptied from the air tank it will then restart. I have had the compressor for some years.!I bought it off eBay and it was only a matter of months old. It was stated that it was an ex display model ???
    It may be better if I take a film of what I'm saying is going on with the machine. If I upload it onto UA-cam I can then let you know the link.
    Might be can be for other people to repair their machine with the same problem.

      One of the first things to notice is to see if the compressor is running. Have someone turn the thermostat off and while you're outside at the outside unit, have your helper turn on the thermostat. You'll want to listen for the sound of the compressor starting. If it starts with a buzzing sound and then stops, then your compressor is kicking off because of an overload. If that's the case, turn the power off to the outside unit. There should be a disconnect next to it. You'll want to check the run capacitor for the compressor as I show in this video. Do that and let me know what your results are. Have a great day!

    • @stuzman52
      @stuzman52  6 років тому +1

      I just used the scale Phillip to know how much refrigerant went into the system. For charging systems, you add the amount of refrigerant depending on whether your system has a capillary tubing, (orifice or piston as it's sometimes called) or if the system has a thermostatic expansion valve. Both of these items are located at the inlet of the evaporator which is inside the air handling unit. On my system, it had an expansion valve which means that I needed to charge the system until the subcooling was between 5-7 degrees F. If the system had a capillary tubing, then you would charge using the superheat which is a little more involved because you have to take the wet bulb temp at the return, take the outside ambient temp and then look those up on a chart to see what the actual superheat should be. So, to know when the charge is correct in my case, I just monitored the saturated temperature on the high side and then subtract off the temperature that's down on the liquid line. When that temperature difference is correct, then you've added the correct amount of refrigerant. Was that clear as mud? :))

      I'm not sure Ali how you made your connections and will clarify the connections between the compressor windings and a run capacitor. You mention a connection to N which I assume is neutral. L1 will connect to the C, (common) terminal of the compressor where the run and start windings are connected internally inside the compressor. The R, (run) terminal on the compressor will connect to L2 or N if you have a neutral. The S, (start) terminal on the the compressor will connect to the HERM, (Hermetic compressor) terminal on the run capacitor. And finally, the COM, (common) terminal of the run capacitor will connect to L2 or N. If the unit still blows a fuse or the compressor trips, you'll want to check the run capacitor. I show how in this video. If the capacitor checks okay, then check the windings of the compressor. I show that procedure also in this video. Hope that helps you out Ali and good luck!
