Fedders Dehumidifier - Wont Turn On

This Dehumidifier won't turn on. The lights on the control panel will not come on at all. I have traced the power to the circuit board in the unit and it is fine. I do not have a parts or trouble shooting manual. Looking for links to manuals and information on how to troubleshoot.

Re: Fedders Dehumidifier - Wont Turn On

Looks like a control board, Check the board for burn marks. What model do you have? Some parts are available on-line at appliance factory parts.. also check your Capacitor and fan motor before you install your new Board..Let me know if this helps? Krazytech

I have a Fedders Dehumidifier that was built in mid 60's. Model DHF.5 that lookes new and used to work great. There is a lamp of some sort in the front panel that would go on when the pan was full....

Light is not that necessary, just a visual indicator. Usually a 120 volt neon panel light that you can get at a hardware store. Modify the mounting hole if not exact and done.

The dehumidifier shut off automatically but will not come back on. Model M7DH45B2A

If the unit shut off automatically, because it had reached the humidity extraction level you had it set on. It won't turn back ON again, until the humidity level rises above the setting you have it on. Lowering the humidity extraction level to 32 -35%, should make it start up again and cycle like it should. If your unit does not have an LED Screen, set the manual control on Maximum.Be sure the bucket is not full and the air intake filter is clean.

Hope this helped you to troubleshoot and solve the problem.

Demudifier worked great, all a sudden it just stopped. No power. Now it won't start up. What should I try?

First, check the outlet that it's plugged into, to make sure that there's still power to the outlet. If there isn't, then the circuit breaker for that outlet has been tripped, in your home's circuit breaker panel. Leave the dehumidifier unplugged and reset the circuit breaker. If it trips again, without the dehumidifier unplugged, then the outlet is at fault. Perhaps there's a loose wire connection or the interior of the outlet is cracked.

If it didn't trip without the dehumidifier plugged in, plug the unit it in,. But, before you do, make sure the dehumidifier's Master ON/OFF Switch is OFF. Once it's plugged in, turn the Master ON/OFF Switch to ON and set your controls. If it runs now, GREAT! If it trips the circuit breaker again, there's either a short in the power cord or an internal electrical short. Which will require extensive troubleshooting to find.

Hope this helps you solve the problem. Please let me know. Thanks.

An automatic overflow switch and Container “Full” indicator light are provided to turn the
dehumidifier off before the container overflows. When the indicator light on the control panel
glows, the water container must be emptied. If the light remains on and the dehumidifier does
not begin to operate make sure the float is attached to the water container.

When the condensate water container is full, the indicator lights up.
1. Turn the power off before removing container. Wait 3 minutes for
any remaining water to drain into the condensate container.
2. Tilt the container forward then lift carefully by the handle.
3. Empty and gently re-insert the container.
Important:This water is not suitable for drinking.

Please rate and god bless:)
