    SubZero 550 runs constantly.  Food cold.  Freezer and Refridgerator door fans do turn off.  This fan - I believe to be the compressor fan - runs 24/7 even when the doors are open.

Condenser fans (the fan next to the compressor) do run all of the time. That is normal.

    If it's normal, is it necessary? Can we hook it up to run only when one of the compressors is going? We live in a *very* quiet location and the noise of the fan is substantial.

Intertherm MGHA-070ABFC-05 will not run/cool


Multiple problems. Eliminate thermostat first. Remove face from wall and turn on breaker. If fan still runs you have a bad board or bad relay. If fan outside is running compressor should be too. These operate on same contactor. Verify you are getting 24 volts to coil side of contactor. If odf stops working and contactor remains pulled in you have a bad motor. If odf motor stops working the compressor will shut off due to overheating.

This sounds like a split system, the condensing unit outside and the evaporator coil and fan inside. You must be referring to the indoor fan, since the compressor and outdoor fan are controlled by the same contacter. The indoor fan relay contacts sounds to be welded shut, and needs to be replaced.

LG Model: LWHD1500ER - I would like the unit's compressor to remain on constantly. The temp guage seems to be off and shuts down the compressor. Can I bypass the temp guage to leave th ecompressor...


You can but the unit will have not control over temperature, and you can cause the unit to freeze up or slug the compressor w/ liquid refrigerant causing premature compressor failure. I would recommend replacing the thermostat if it is not holding proper temperature, but if dead set on bypassing it use a volt/ohm meter after unplugging it to find the normally open contacts and wire those wires together taking into consideration that the fan must run constantly with the compressor.

Why does the fan run non stop? the compressor runs and shuts off but the fan just runs on high and low. I have 3 other dehumidifiers that the fan runs only when the compressor runs...why doesnt the...


Depending on the time sequence you have this unit set to run, Fredrich's are designed so that the fan runs almost constantly, to keep the air moving. When it senses a rise in humidity above the level you have it set on, the compressor turns ON and runs until the level of humidity is lowered. This is especially true, if you are operating this unit in continual mode.

Hope this helps you and thanks for choosing FixYa.

A/C blows good cold air and everything works as it should, however when I turn the A/C on (doesn't matter what fan speed) I hear a constant clicking/ticking noise coming from what sounds like a fan


What you are most likely hearing is the compressor kicking on/off. The constant kicking could be a sign that there's insufficient refrigerant to keep the compressor running continuously without shutting on/off. Eventually, the compressor won't kick on at all, a safety feature designed to prevent doing damage to a compressor that's undercharged. Have the AC system checked.

Cooling fan keeps running after the engine is shut off


Does it eventually shut off or does it constantly run 24/7. If it only runs for a few minutes or so after vehicle is off it usually is cooling the engine after running for so long.

I have a beverage air kegerator that seems to work fine, but the evaporator fan runs constantly. Is it supposed to run constantly, or is it supposed to cycle on and off with the compressor, etc.?


Most evaporator fans run all the time. This is mainly to use the air flow to assist in melting off any frost build up during the compressor off cycle. If that fan shut off with the compressor the coil will have a tendency to freeze up. :)
