The Main reasons that this will happen
1 - A bad run capacitor (silver or metal capacitor)
It’s either shorted, grounded or open.
If it’s shorted a lot of times it will bulge out, (sometimes slightly)
2 - A bad start kit ( plastic capacitor and Relay connected to it )
The capacitor is either shorted or open
The relay either has an open coil between terminals #1 and #5
Or the relay is stuck.
Any time you change the capacitor or relay you should change
the other, especially if they are over a year old.
3 - A loose, burnt or disconnected wire
4 - Wired wrong
5 Compressor is open (windings burnt open)
6 Low on charge not getting enough cooling back to compressor, (Feel top of compressor to see if it’s hot it shouldn‘t be)
7 Some compressors have a black plastic overload under the compressor cap which could be bad.

Edison 40 fan starts -then trips breaker (before compressor kicks on)...toast?


Maybe..but what else do you have on the same circuit? Could be overloaded by another appliance. Make sure you unplug all items on the same circuit, then try it again. If it still blows most likely its in the unit, if if runs with no problem, issue is overloaded circui, too many other things on the smae line.

2 yr. old. worked great. Then started shuting down self changing setting to low. shortly after, shuts down after 3 min. no water collection, unit is hot. Took apart. Cleaned everything inside, and filter....


Robinson, it really sounds like the compressor is overheating. This may be caused by a low refrigerant gas in the compressor. Or the compressor's oil has leaked down. But, if you took the unit apart to clean it, I would think that you would have noticed an oily residue. If it is the compressor (other than needing to be recharged) it would cost almost as much to replace it, as it would be to buy a new unit.
At least with a new one, you'd have a one year warranty and more, if you purchase an extended warranty.

Hope this helped you.

Have a ge humidifier and when it is running there is a power draw every 4 min


Hi,
The compressor is trying to start and cannot... the overload kicks out and then cools down... the compressor then tries to start again...

It will cost more then a new one to fix...

Fan kicks on but compressor does'nt start. Humidity control checked out. Compressor ohmed out. Fan runs for about a minute then it shuts down.


i would do a continutity check on you relay and overload, other than that
what is the humidity level in the room, as well as the ambiant temp. these mahines cycle for that very reason, the fan will come on, do a check and then determine if it should start the compressor.
check if you have voltage at the compressor when its supposed to be running ( just a last thought)
ive seen compressors ohm out, but in fact be bad

Dehumidifer runs for about 45sec to 1minute and then shuts off. wqhat would be making this happen


If it does that consistently, then it's likely that the compressor is overheating and shutting down. (It has a thermal overload circuit to prevent a potential fire). Another cause could be a malfunction of the control circuit board which runs all functions of the unit. To check for possible compressor problem, unplug the unit, remove the housing to expose the compressor, plug it back in and power it up. When it shuts down, feel the compressor. It should be warm to the touch, but definitely not so hot that it singes your fingers.

If you find that the compressor is just normal warm, then the control circuit board is shot and needs to be replaced. Check with the merchant or manufacturer for availability & cost. If prohibitive, you're better off simply replacing that unit with a new one.

My Kenmore had the problem of the fan running, but not the compressor. The compressor overload part was bad.

Dehumidifier shuts off after 2 mins


you might have a compressor problem, in which it won't be economical to repair. if you are using the unit in cold weather then it just might be that there is not enough humidity in the air and it is cycling fast.

Haier HDN655E unit runs but compressor won't kick in


use a jumper cord and go directly to the compressor to see if it will run. if it don't run, open up the motor box and see if there is a klixon overload inside. this should be normally closed. if it isn't replace it. the klixon is a thermal overload cutout. it usually trips because of high winding temperatures and protects the motor inside. the compressor is a hermetically sealed unit. no, or little freon will cause the motor to overheat.

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.
