Re: Compressor won't run
The over-current relay is tripping out the compressor motor to prevent excessive current through motor windings. To prove this theory, open unit, find motor wires, disconnect wires from unit, and apply 120VAC to motor using external circuit-breaker source. Run 2 minutes max. If motor continuously turns, then relay is failing. Find it by tracing wires back to source and finding a small rectangular item. If motor again quits after 2 seconds, then this motor has an internal over-current self-resetting fuse that may be doing its job of preventing an electrical overload from a dead (shorted) motor.
The compressor of my refrigerator make a noise but won't start.
I install a 3 n'1 Start (solid State Relay Overload Start Capacitor Combination)_but tyhe problem remain the same.
I can I check the compressor.

The temperature sensor can be broken or because it is an old unit is the freon gas can be escaped by an internal leak in the compressor circuit and thus no longer works, there is a part to be internally freezing when the compressor is running. dismantel to look also if thereis somewhere in the circuit a solenoid-valve to find that will not get dc function by electronica.
So I just had this happen with my Frigidaire fad704dwd dehumidifier. I went to basement and heard it running and sounded off. The compressor was running fan was off which is bad and humidity said 30. I then pushed the off button and it stayed running. I was able to fix it. To make long story short it was a bad ground. I took the plastic back, sides, and front off. There was a green ground (main ground) and Green/yellow ground (fan ground) on the front coil with a bunch of rust. Removed the grounds connected them both together and cleaned the surface area and used a new stainless screw nut and screw to remount the wires to evaporator coil. Everything started working fine after that and I put it back together. Good Luck
Kathy, I'm not sure you have a problem with the dehumidifier. Depending on which mode you're operating it in, the fan will run in an effort to recirculate the air. If the humidity level rises above the level you have the unit set on, the compressor will then turn ON. This is particularly true, if the unit is operating in continual mode. Then there are other times the fan isn't active, but the compressor turns on when the humidity sensor feels a rise in humidity. So, for the most part, I don't think it's a problem.
Just be sure that you clean the air intake filter at least once every two weeks, during times of daily operation.
You most likely have a freon leak, or the compressor is not running. When the machine first turns on you should be able to see if the compressor is running or if it is just the fan. If the compressor is not running it does have a start devise and a relay on it that can be replaced. If the compressor is bad, most units have a 5 year warranty on the compressor, so contact the manufacturer for warranty service. If the compressor is running you have a freon leak, and it would need to be found, repaired and the freon replaced. This is a large repair, estimated charge for a leak repair would be around $149.99 The reason is the long time it takes to find the leak, and all the parts needed. Drier, valve, freon, etc.. Good luck, and I hope it is only the relay. You can get those relitively inexpencively. 3 in 1 kits are also good for a hard to start compressor. They give the compressor a little more kick to start it. They are about $28.00 and easy to install once you are to the compressor. I hope this will FixYa.
Sorry to be vague in advance. I am a bit confused as to the compressor seems to be running bit. If the unit is on you should hear the compressor making a continuous noise. What you have described over a relay going click every fifteen secs could be the compressor overload / relay. If it is then the compressor is trying to start hence the dimming lights. Either way I would suggest one of two scenarios either the compressor is faulty or cannot start due to the relay or the unit is short of gas. Eiher way not a good scenario. I would suggest a tech to confirm or spend the money towards a new unit.
Hope this helps.
Save the old one for parts if you get the same new one but I def. don't reccomend buying this unit again. The reviews are bad. The fan is not covered under the warranty except first year or extented warranty. I spoke with Kenmore & Sears about this to see if coverd under 5 yr. Only compressor,tubing & refrigeration system(see inside of front cover for warranty info.)
Sound more like a sensor/circuit board problem to me since fan is turning. I think the signal determins which setting fan needs via sensor assembly to run. I could be wrong. Justa thought.
Can you def. hear the compressor come on. You can look through grill to see fan spin & the compressor makes a clank/clunking noise/ The fan & compressor should turn same time. Good luck! If you got any info. on my fan problem & you have update or fixed your problem I ccould use some help. Check post for my problem.. Thanks! panfan1
