Hello,
I have a used Midea Washer Dryer combo in a closet on 120V in RV with surge protection and 20 Amp breaker. Error E64 started after we used it for three months. E64 means "Signal between Main PCB and Inverter PCB abnormal". I removed the inverter board and found a burned / blown out thermal resistor. I cannot tell the type or specs, so I'm not sure how to replace it. Midea said replacement parts were designed and made in China. Midea has replacement for $135. I found replacement part on Google search with a 820 Ohm resistor in place of the thermal resistor.

The resistor is in parallel between the relay and rectifier and in parallel with transformer and rectifier. I think the replacement resistor is a 4 band Grey/Red/Brown/Gold, but I do not know what the power requirements need to be. If it is 820 Ohms at 120V, then that would be .15 Amps and 18 Watts.

I would like to replace the resistor and add a fan to circulate air around the W/D.

Any suggestions?

Thank you,
Tyler

Hi,
I'm staring at E64 as well, and the thing is stuck with my clothes inside and an unlock icon (not letting me open the door, though!)

How do I remove the inverter board-- I figure an obvious physical check like above is a good place to start!
