Goodman Unit Won't De-energize

[jogosan]

2 yearold goodman unit. HP the unit runs fine until it satisfied. Contact pulls out Compresser shuts down ,fan also but reversing valve won't de-energize.
When unit attemps to start it trips the breaker. All wiring was checked out, everthing looks good This is the first time I've encountered this problem Can Some One Please Help If I switch the TStat to the off position it de-energizes.

Thanks

Sounds like some kind of stat problem (Wiring )check the switches in the stat What kind of stat brand name would help

[jogosan]

Replaced Tstat With a Carrier HP digital

[dugfish]

On the back of the stat there is a dip switch A/C or HP is that ok

[jogosan]

It's A digital TSTAT And I configured Tthe Hp on as well as all the other little things you do to these new TSTAT. It had a mercury TSTAT Honeywell

The reversing valve doesnt deenergize everytime the stat satisfies. It stays energized as long as the stat is in the cooling mode whether actively running or not.

yes unless you physically move your thermostat to off or heat it wont denergize. It doesnt need to as long as your still in the cooling mode, but just satisfied on temperature.

If I pull the wire off the 24 volt on the reversing valve coil it will de-energize.

[jogosan]

When it call for cooling it trips the breaker if i don't switch it from cool to off, then back to cool after it de-energizes

check for loose wires or weak capacitors. If nothing here then you might have something going on with the compressor which will eventually seize all together. good luck

Does everything work without t-stat meaning can you energize and go through the sequences with the t-stat off the wall or jumper between circuits? If so you have a bad t-stat. If you isolate something that you think is the problem and you can get it to work without that component in the circuit then you have found your issue. Also don't dome heat pumps have a normally energized 4 way and others have a normally de energized 4 way...the reason for brown wire or orange wire...One is used for in the cool mode 4 way switch the other is used in the heat 4 way switch....am I wrong?

Thanks for all the replys . I changed the Tstat Thinking that was the problem but I'm not what some may call a parts changer. I like to get to the problem and fix. Thats code on my book . When stumped I always come here. But to be honest it's been awhile that I.ve asked for assistance here at HVAC-TALk . Thanks Again

Do the pressures equilize in the off cycle? That is the first place I would start. What type of metering device does the evap. coil have? If it is a TXV, is it for a HP and does it have an equilizing tube? Is the run capacitor for the compressor good? Does it have a start kit on it? I dont know of any stats that de-energize the RV when it satisfys (not to say they arnt out there, I just dont recall any) they keep the valve energized unless you turn the stat off or switch to heat.

[todouble]

usually around here you have units energize the RV to cooling which all mfg's use differant colors but orange is most common. This way when it fails it goes to heating in case its in the winter months u dont wont ur RV to fail in cooling mode

Sounds like it has a non bleed TXV on it.
Other wise, the reversing valve being constantly energized would not have any effect on the compressor restarting.

If thats the case, you need a hard start kit.
