Question about Goldstar DH304 Dehumidifier
This unit has always performed well but when we turned it on this year it shuts off within a minute or two. The filter is clean "What's Up"
The fan turns on, runs for a few minutes, then turns off?
It's your humidity sensor. I'm still trying to find a replacement part, but you can trick it into running by removing the front panel above the water collection tank. You'll see a little sensor mashed into the coils. Remove it, unplug your red and black stripe wires, tie them together, push them back into the middle slot (the same one the black stripe came out of). Soldering the connection would be best, yet I didn't have a soldering gun so I just mashed it in there.
Unit works like a charm....yet the dial on the front for the "control" of how much humidity you want to remove is bypassed.
Side note: Not sure what saftey implications this solution produces, yet the float sensor still works in this setup. Also I don't beleive just tying the two wires together will work, as there is a resistor in the switch. The red wire is clearly the switch leg, resistance is measured through the black and the black stripe. You have to keep the black wire in it's original spot to force the voltage through the resistor, and then when you tie the red and black stripe together, you're getting the "turn on signal" all the time, while keeping the required resistance. I did not try tying all wires together minus the resistor, as the wiring diagram clearly showed one and it was easy enough to keep it in the loop.

I also think that I have solved this problem. Soldering the black and red wires going into the humidity sensor (sensor clipped on the coils of the humidifier) did NOT fix the problem for me, for whatever reason. After this didn't work, I removed the metal cover for the dehumidifier to expose the guts of the circuitry. I found where the red and black and white wires from the humidity sensor connected into the the main "motherboard", and simply pulled all three wires out. This seemed like the quick and dirty solution to inactivate the humidity sensor! And presto, as soon as I did this, the unit kicked on, and will now run until the bucket is full.
