Question about Maytag M7DH45B2A Dehumidifier
I checked the motor and it was clean on the inside and out. I can turn the motor shaft manually. I also checked the fuse and it was fine. All the electronic parts appear in working order; the circuit boards are clean and clear. The fan just won't work on either high or low settings. There doesn't apear to be any undue burning of fan motor components to suggest a short circuit or burn out. Would it be worthwhile to buy a new motor or could there be another issue? Thanks.
Comment by fisherm456, posted on Jul 14, 2008 ALl the wiring is fine. The boards are fine. The fan wiring is fine both inside and out. Comment by fisherm456, posted on Jul 14, 2008 The fan blades turn just fine. I even took the motor apart and it's clean. All the wires are connected, the fuse is fine, the compressor works and all the bells and whistles work; it's just that the fan motor will not turn. What could be the problem? Thanks.
It gets a little tricky from here! If it were mine, and with my experience - I would try to measure for power going to the motor, but that may involve more dismantling. Dangerous voltages are likely to be present so don't attempt this if you are not qualified to do so! If there is power going to it, then logically the motor is defective. If there isn't , then it points to the control circuitry. In the former case a new motor might get you going again - if you can find one; if there is no power going to it then the fault lies elsewhere. If you are very lucky it might just be a dead relay on the pcb. Beyond that point I have learned over the years that some things are just not designed to be fixable :-( The pcb may have been made years ago in a factory on the other side of the world and we consumers are just expected to go out and consume a new one dehumidifier.
Hope this helps a little bit. D
