The unit model # is A3DH3032A Rev-A-R. The unit's fan runs, but no water is collected. Thanking you in advance for this support line. Frances

My brand new frigidaire 50 liter dehumidifier has been on for two days and has not collected water from my damp basement. It is on the factory settings: high fan and "CO" (continuous).

If it is not blowing out air from front grill then fan is burned out and needs replacing - $50 do-it-yourself (lots of disassembly) $100 for them to do it. Is it still in warranty? (1-2 years for fan/sensors))

I have a Whirlpool dehumidifier model AD50LJ0: the compressor starts but then appears to trip out. The fan keeps running. It does not condense and water. Can you help?

I am still unsure here if your saying that the fan motor is running with the compressor or not? can you clear this up for me.

It appears that these units have a history of defectiveness. I bought one in late 2010 and it pooped early 2012. If the model is still made, buy a new one, return the defective one in the new unit's packing materials for a refund. Or keep the second (new) unit as a back-up, because the new (first) one may just fail again a short while later.

Hate to tell you, but it may be a goner. Many units have a rectangular air filter that may be clogged, but I would still expect to see some moisture removal. Without exact model I'll have to be general,.... remove cover (front or back, depends on model) to see cooling coils. If the compressor is running, these coils should be wet or may have a light frost on them for a time. Not = refrigerant leak. (not economical to repair) If you see one small area of ice,... it's also a goner. If the compressor does not run you could have a bad compressor, a bad defrost control, or a bad control / humidistat. Other than the filter or possibly a fan motor, these unit are rarely economical to repair.

If everything is running and no water is being produced the system may have lost its refrigerant. There are two motors in dehumidifiers. One is the fan and the other is the compressor. Make sure they are both running.

By condenser I assume you mean the compressor is running. Is there ice forming on the front coil?

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.

compressor may be starved for freon or blockage in freon line...tech must troubleshoot.
