AC question..... My turn

Capt.EdCapt.Ed Posts: 368 Deckhand
OK guys I have a good one for you.
I have a Rheem 5 ton unit (2005) last year while using the AC (not the heat) it decided that it would jump into the heat defrost thing??? of corse this pumps a little hot air into the house and Then it trips the reset button on the outside unit.
If I wait about 15 minutes and push the reset button, it comes back on in cool mode and runs fine until it decides to do it again.
It does this randomly sometimes once or twice a week and sometimes 3 or 4 times a day??? There is absolutly no time pattern to this happening.
I have had 3 different AC companies out and none can find the cause.
The first company charged the freon and cleaned all the electric connections but the problem continued. The other two AC companies just stand there scraching their heads and wanting to install a new unit.
Of corse all three want to install a new unit. But other than the unit having it's little fit, the unit runs fine.??????
Any ideas?:huh:huh:huh

    Yeah I know and I'm in no hurry.
    I have no problem paying anyone to FIX the problem or even paying to install a new unit.. But it will drive me crazy if I can NOT find the cause of the problem... My OCD kicks in and I will go nuts :-)

    Not saying this is the answer as it probably isn't, but when I get squirrely electric problems like this the first thing I do is check the grounds.

    Sounds like a bad defrost board or possibly the temp probe from the board. Some of us A/C guys work 24/7 :wink

    Hey Ed, the last thing you need is a new unit. I would report those companies to the BBB. Every thing in the system is old school except the circuit board. I'm sure that is the problem. Although I have been in the biz 42 years , never seen this happen in the cool mode, but doesn't surprise me. Circuit boards and sensors can do some odd things. As long as you don't have any shorts in t stat wires it is the circuit board. Call a service company not a sales company.
    Your welcome. :)

    It could be the reversing valve is being energized when it'd not supposed to.
    But I think it is more likely the condenser fan motor or it's capacitor it going.

    OK guys I know it has been a while sinse I posted this.
    Right after I made this post the AC unit decided to act normal for 3 weeks (it's longest stint in over a year)
    Anyhow I didn't want to post or say anything in fear of jinxing myself....
    Then last tuesday night it started it's crap again... going into defrost mode and tripping the reset button.
    Wednesday it decided to blow both cold air and hot air at the same time, you could feel the cold air on one side of the vent and hot air on the other.
    I called a buddy of mine that owns an AC shop, he found me a circuit board in his shop and came over and replaced mine.
    AC MAN you were 100 percent correct sir.... thank you :USA
    My AC is now normal again and I will not have to smash it with my backhoe :mad
