I had the dehumidifier running. It is only a couple of years old and rarely used. I emptied the water and slid the tray back in. I pressed the on switch and it turned on and then turned off and it won't turn back on. I've checked the plug and electrical box, thinking I might have a circuit breaker problem but no luck. When I press the on switch on the keypad, I don't hear anything click like I do for other options on the key pad.
The fuse is not really needed. Look at the sticker on the compressor in
the back and you will see it is rated at 30 LRA which is locked rotor
amps. Obviously if the compressor fails to start instantly for any
reason that 30 amps is going to blow that 12 amp fuse (which is a fast
acting instead of a slo-blo for whatever dumb reason).
The fix is simple, move the black wire that comes from the power cord
from the terminal marked L in the lower right corner of the board to
the unused terminal marked common on the big relay in the lower left of
the board directly above the fuse. This will bypass the fuse and allow
the thermal cutout on the compressor itself to do its job when the
compressor fails to start due to short cycling.
I just had one of these units given to me because it was DOA and when I
found the fuse blown I figured the compressor was shorted but after
performing this fix the unit works perfectly and is drawing a normal
amount of power according to my Kill-A-Watt meter.
The 12 amp fuse is blown
Daniel has you bypassing the quick blow fuse....It's okay for testing, but you should have an amp meter and if that shunt takes longer that 5 seconds @4x the running amps. Then it's time to shut down and take in for a full analyze. Otherwise, if something like a fire happens..I mean a BAD FIRE, You would find yourself in a world of ********* with the Fire Marshall and the NO desk of your insurance provider. You bypassed the UL and they'll get you....
When you "...pressed the on switch and it turned on and then turned off and it won't turn back on...", was this done in rapid succession or was some time allowed between switching? if rapidly, the micro inside "locked-out" the keypad for starting, to prevent compressor damage. if not rapidly, then look inside for a possibly a starting relay...did it used to "click"?
