Amana dehumidifer blows fuses

I have a 2? year old Amana dehumidifer model D545M located in a vacation home. Unit was not working, (completly dead), disassembled and found a blown fuse. I replaced the fuse and turned the unit on. The fan turned on for about a second then blown fuse again. I then jumped the fused line (to direct wire), to try and determine what the problem was. The result was the same, fan turns on for a second then before the compressor starts circiut breaker kicks out. I have had no other problems with this unit before. Since this is not at my primary home I do not know if there were any noises or problems just before the fuse went. I also have same unit at primary home and have had for about 4 years with no problems at all.

I have an amana d545m in the crawl space at my lakehome...when i went to check on the furnace filter, i noticed it was not running and has no and what do i check to diagnose the...

First, make sure that there's power to the unit. Has a circuit breaker in the circuit breaker panel been tripped? If so, unplug the unit before resetting the breaker. Also, check the receptacle or extension cord that you're using to power the unit, as it may be damaged.

If you have power to the unit, it may be that some critter or insects have gotten into the unit and shouted it out. In which case, you're lucky that it didn't start a fire. It's not a good idea to leave the dehumidifier running unattended for a week or more.

Hope this helped you troubleshoot and solve the problem. Thanks for choosing FixYa.

I have a two year old D545M dehumidifier that has stopped dehumidifying. The fan operates, but it is not removing any moisture. What could the problem(s) be?

I have the same problem--no water comes out.

make sure the front vent/filter is clean and free of debris. if there is not sufficient airflow across the condenser coil (front), it will not cool down. if it does not cool down, it won't remove the water from the air.

AmanaD545M Runs but no water comes out

if the compressor is running and the coils dont cool, then you have a refrigerant leak or a plugged capillary tube. it would cost more to fix than to but a new one. sorry but its time for a new one.

Amana D530M Dehumidifier won't run

We all appear to be in the same mess --Thanx Haier
This product says its Amana, but rest assured it is an Haier
The problem is most likely with the engineering design of the board. Im not an electrical engineer so be careful litning to me to closely :) There is only a half bridge rectifier on this board and 2 zener diodes that clamp down on the voltage. My guess on yours is the Zeners have been shorted and no longer clamping voltage down to aroun 24 volts for the low side of the board. I spoke with Haier and they have no schematics that state the zener specifications. They also said there was a 6 month backorder on ordering a new board. Oh and by the way if you want to order a new board and wait 6 months for the backorder it would cost you 75.00. All this jsut to repeat the problem again, because of bad design. O well ----- I wish products were not made better, so I wouldnt have to fill guilty about putting this in the landfills.
