About the only thing you can do without a service tech looking at the unit is to check the capacitor. If it is bulging it has blown and you'll need a new one. If you are not comfortable working with electricity I'd take it to someone because, even unplugged, you could get harmed or worse just from handling the capacitor.
If the problem is not the capacitor and the unit is getting power the chances are good the compressor itself has blown and you'll probably be better off buying a new unit rather than bearing the cost of a comrpessor replacement. That choice is, of course, up to you.
Good luck.

I have H. Bay model HB40F dehumidifier. It does not seem to ever actually start the compressor. There is a plastic box on the side of the compressor that contains a couple of coily looking things. It...


It is probably the start device(the coil looking things), as long as you don't hear the compressor humming. A loud hum is a lock compressor and the cost would be far greater than a new unit.

Fan runs ,coils are room temp. should they be hot or cold , no water is collecting in bottom


A dehumidifier is basically an air conditioner, so some coils should feel hot, the others should feel cold.

If no water is collecting, then the unit's compressor is not starting. Typically you have four possible failures causing this: the switch/wiring for the compressor has an open circuit, the motor-start capacitor for the compressor has failed, the compressor itself has failed, or all the refrigerant has leaked out.

If there is evidence that it is 'trying to start', but then clicking repeatedly, this can be a symptom that the refrigerant has leaked out, as some devices have a pressure switch to prevent compressor damage.

Also, a failed start-capacitor can also cause the click-click noise if the device has a current limiter switch on the compressor.

So the short answer is, it's broken :)

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

Seem like the compressor is not working very hot


Assuming this is the A/C compressor, right? The compressor will be hot to the touch, the question is whether or not it is engagining when turned on, Check to see if the compressor clutch iis working by having someone turn it on and off while listebibg an observing the compressor clutch. Low refrigerant would or should orevent compressor operation to protect the compressorthrough a safety switch. Good luck

LG LHD30 the compressor does not cycle on


Compressor won’t Start
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.

Compressor does not start


some of these units have a 5 year compressor warranty on them including labor worth calling sears and seeing if it does have the 5 year on the sealed system
