It's likely that the contacts are stuck closed. You can usually just tap them with a screw driver and they will open but then you should replace them. If you don't know where they are. Find the power wires coming inside the unit and follow them. Contacts are fairly easy to replace as long as you do it wire for wire. In other words when you remove a wire from the old attach it to the new before removing another. I hope this helps. Please don't forget to give me a Fixya rating.

SOURCE: ATWOOD MOBILE FURNACE RUNS WHEN IT WANTS/

Check your furnace for power. will be 4 wires. power ground and 2 thermostat wires. Check for power at the time delay relay, if you have power there check for power going in the fan motor, if power in motor wire, motor is bad. If no power in motor wire and power going to circuit board take the 2 thermostat wire apart and wrap the 2 together comimg from the thermostat. Fan will stat in about 30 seconds. If it does you need a control kit in the ac. But sounds to me like you have a furnace problem.

SOURCE: Turned AC thermostat to Cool today - AC didn't

Just clicking is all your getting from ceiling assembly? No other modes work such as fan, or furnace? If that's the case, check your circuit breakers to make sure it didn't trip.

SOURCE: AC compressor will not engage

It could be the capacitor, it could be a loose wire connection, it could be a delay switch or a contactor/relay.

SOURCE: Rooftop RV Air Conditioner: replaced capacitor on dometic 59516-531 steal trip...

You need to borrow a clamp on style amp gauge, and check amp draw on black wire in box where hydro wires connect. (PLEASE, be careful, and if not experienced in this type of test, don't try it, due to likelihood of getting a shock. ) If it's the compressor kicking in that's causing the breaker to trip, and capacitor is good, then it's usually a problem with either low incoming (supply) 110-120 AC voltage, which will cause high amperage draw, or compressor on it's way out causing high amp draw. If it's only drawing 15-18 amps, and your tripping a 20 amp breaker, then breaker is getting weak.

Freezer working, fridge isn't.


It is possible that your cooling unit is failing due to a blockage. The solution used to cool starts at the top of the fridge and works its way to the bottom. If there is a blockage in the cooling unit it could produce the symptom you have explained.
