      Are you positive it wasn't a hp lockout? I couldn't see the flashes. It's really common for Rheem to hp lockout at the beginning of heating season. 60 plus outside temperature with low airflow will do it. Clogged air filter, dirty clogged evaporator or fan motor.

      If I would have seen that high of pressure on low side, I would have checked amps. With the 77 degree inside temperature it seems that the pressure would have been lower. I thought just from pressures it may have been a bit overcharged. If capacitor ( if it was a psc) was weak on blower motor…that could have led to a low pressure situation by lowering fan speed. Did you figure out why it was faulting?

    I'm going with a squirrely x13 or that stupid blower relay they use that's like the Goodman relay. I've replaced a couple of those. There was water gurgling in the drain trap, that could have possibly been from ice melt?
    On the flip side of that, I had a unit freeze the entire coil into a block of ice and the entire line set and all the way out to the compressor and the unit was still running and did not trip low pressure. 😵😵😵

    @s.c.588 Рік тому +1

    The board, pressure switch, depending on the type thermostat loosing G will cause that, the air handler circuit board loosing G and a failing evaporator motor/and or capacitor if it has one. And also bad relays for the evaporator motor if it’s a PSC motor and running off a relay instead of a board if it’s an older unit. But most have all of course switched to circuit boards long ago. But if it’s an indoor issue with the blower motor or it cutting off the coil of course would be iced up. And there are other issues that will cause that problem as well but they are rare. I’ve had some to drive me nuts before i found it. Expansion valves shutting closed are a rare occurrence but will cause that.

    I'd prob just bypass low pressure switch. Does it again it's definitely the board. Come back out and frozen or not cooling. Then it's blower or txv...very rare issue would be a closed evap circuit. Slowly freezes up after day or two.

    on Wednesday I had a condenser unit that would not start. The code was locked out on pressure. I went to touch the compressor but it was cold so I put on gauges and the charge pressure seemed ok. I was going to test the cap when I notice my common from the board was burned out. I had it running for 15 minutes and took an amp reading and called a day.

    Thanks for the video. So LPS, defrost Board, Blower failure, TXV is our options lol. Let us know what happens. I’m leaning toward blower. I’d bypass the switch and board and if it actually freezes up than it’s gotta be the blower. TXV’s usually don’t unstick. If a while passes with no issues than at least we know the issue 🤪 by that time you’ve spent too long lol hate intermittent issues!

  • @denrayr
    @denrayr 3 роки тому +4

    What a stupid design. The control should resume operation automatically once the fault condition clears. Do you think they might have had a dirty filter? What do you think about jumping the lps circuit on the board, then rewiring the lps to be in series with the yellow wire input to the condenser? This way you'll eliminate nuisance lockouts while maintaining the ability to cut out during a low pressure condition. If the board locks out while bypassed, then you know the board is at fault. If you have some other intermittent issue, it will eventually get worse, so it can be identified.

  • @jkbrown5496
    @jkbrown5496 3 роки тому +1

    Does the LP lock out require resetting the board or will it auto-clear? My HP switch developed a resistance across it last Spring. Initially, diagnosed as a bad board because of flash code confusion between the comfort alert (on schematic) and the board flash code (on a sticker at far extreme from schematic). I doubted the diag so tested the pressure switches and found the HP had about 15 ohms across it going up to 30 when running where it shut off. Oddly, the unit would work from sundown till a couple hours after sunup.
    Long story short, they came with a board and HP switch, confirmed and changed the HP switch. Small hairline crack was found on the switch.
    With the recent AT temp changes could there be a hairline crack in the LP switch that opens when it gets colder? Might be worth changing the LP switch is cheap for the customer. Or put your meter on the switch then chill it somehow.
    I had a similar issue with my internet. Twice a year or so it would get sketchy but for several years they found nothing except that it couldn't handle the higher speed service. Then one year, the tech found a cracked insulator at the pole that would get pulled open when it was colder and windy.
