Question about Fedders A7DH45B2A Dehumidifier

1 Answer

Fan runs but no water, I suspect refrigerant leak, coils are clean, so is filter

Is it cheaper to have the leak repaired or just buy another dehumifier. Seems a waste since everything else works great.

    by leak I mean refrigerant leak. I read it on another post. The only thing collecting water is the sensor or coil on the side of the fins. but it is not collecting water

My experiance when I ask my Heating and air conditioning guys when they were out serviceing my home air conditionion was a resounding NO not cost effective these units are practically considered throw away,with no value after 3-5 years no matter what price range and this is true. They say the cost is purchacing and adding the valve needed to refill. Just another prime example of total waste and disposable world we live in.

What is wrong with a Westpointe dehumidifier when it stops removing water and displays P1? It will run this way for hours and kick in and work briefly once in a while on continuous.


Usually the P1 error indicates that dehumidifier needs to be defrosted. The unit has detected ice build-up on the condenser coils.

Unplug the dehumidifier for several hours. Then plug it back in. If the problem recurs, check that the fan that blows air across the coils is working properly. Make sure that the room is not colder than the operating range of the dehumidifier. If the problems continues to occur, you may have a refrigerant leak in the system. That will require a service call to repair the dehumidifier.

If the unit is under warranty, contact Westpointe. The manual I have for a Westpointe 65 PT dehumidifier, https://www.appliancefactoryparts.com/content/pdfs/136333-1.pdf, indicates the unit is covered through year 5 after purchase for a refrigerant system. For Warranty service, the contact point is Midea Consumer Service at 1-866-646-4332. If the unit is not under warranty, consider whether to replace the dehumidifier.

I hope this helps.

Why is my dri-eaz drizair 1200 dehumidifier freezing over?


There are two major causes of a dehumidifier or air conditioner to freeze up the evaporator coil. First is lack of air flow try cleaning or replacing the air filter if it has one; make sure the fan is running and the coils are clean. Second is a low charge of refrigerant requiring a refrigerant leak check; repair and recharge. A slight overcharge will keep a dehumidifier from freezing in cooler ambient temperatures.

The rings on the back are turning to ice when i turn it on.


The rings on the back, that you are referring to are the cooling cools. There are several things that can cause this problem.

1. The air intake filter needs to be removed and cleaned.

2. Obstructed air flow. Maintain at least a 12" to 18" of clear air space around the entire unit.

3. The cooling coils are dirty and need to be cleaned. You ca do this by wiping the of with a rag
moistened with warm water and then wiped dry. Then a apply a light coating of WD40.

4 The air temperature at floor level is colder than at chest level. This is particularly true in base-
ment applications. Dehumidifiers do not work well at temperature at or below 40 degrees F.
Unless it's a Low Temperature model, which are designed for basement applications. In your
case, if you're using it in a basement, raise the unit up off the floor onto a sturdy table, counter
top,etc, that's strong enough to handle the weight of the unit, plus a full bucket of water.

Mechanically, there may be a small leak in one of the cooling coils, which is allowing refrigerant gas to escape and it's frosting the coils. If none of the above solves the problem for you, than I would suspect the refrigerant leak. In which case, it's less expensive to buy a new unit, than it is to repair it

I hope this helps you to troubleshoot & solve the problem..

It is not extracting water, though it is running. The coil ices up almost immediately. Is the compressor dead?


if the temp of the area it is in is not too cold and the coils and filters are clean, then it may have deleloped a leak and lost some of the refrigerant charge. i would clean coils and filters first.

Compressor runs but coils don't get cool to shed water


if the compressor is really running (not just the fan) and it doesnt cool the evaporator coils then it has lost its refrigerant (likely r134a) .. thats a special job to repair.. there also has to be a leak that must be repaired .. then the system is refilled and possibly a dryer added .. if the fan is running only, then there are many other possibilities .. .. you shouldnt run the unit long since part of the cooling for the compressor comes from the refrigerant .. it will shorten its life if run a long time without it ..

Unit runs but doesn't pull humidity out of room, filter clean


Possibly lost refrigerant from system- check warm air is coming out of machine. Otherwise it could be dirty filters, and not getting enough air over evaporating coil. Other than this, replacing parts is usually more expensive than buying a new dehumidifier :(

Unit is repeatedly freezing up


Almost all dehumidifiers now have automatic defrost, but if you are seeing frost is just one small area, it means there is a refrigerant leak. Check your warranty to see if the sealed system is covered longer than one year. Generally, if it is, most manufacturers will replace the unit (rather than repair it, as the repair is rather expensive compared to the cost of a new unit). If you do not have any sealed system warranty coverage left on it, don't fix it. Buy a new dehumidifier.

The coils on my dehumidifier are frosting over.


Are the coils clean? If it has a filter is it clean? If yes to both, it has lost (leaked) refrigerant and it's time to buy a new dehumidifier. If the leak can be found it probably wouldn't be repairable and would cost more to fix than it's worth.

Not working


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.
