Question about Haier HDN305 Dehumidifier
Haier model HDN305. Unit won't run. I tested the fuse on the circuit board and it was good. I tested the tank full switch, fan switch, humidifier switch and they all tested good. I by passed the 110vac to the fan and it works. I then by passed 110vac to the compressor and it ran fine. I think the problem may be in the main circuit board but I don't have a schematic to test it. Is it worth buy a new circuit board? or could there be something else I missed.
After all that testing you have diagnosed the problem. It is the main circuit board. So there is not reason to do any more test. I would just get a new control board and off you go
