DH30 - Instructions

Took the cover off and removed old sensor the new one plied wright in no problems anyone can do it

Replaced the sensor and solved the problem. I had a lot of difficulty with the case holding the circuit board,etc because no easy way to service. Seemes they could have made it easier with a removable panel. I actually cut the wires and re-attached the thermister later after routing. Did not use the other parts of the wiring.

Note: The error code and bucket full indication is a result of a malfunction in the sensor assembly (p/n 6877A30013M. To replace the sensor assembly, do the following: (1) remove rear panel; 2) remove the front panel cover and remove bucket; 3) remove main cover (covers center of unit); 4) Remove cover over PC board on top right side of unit looking at it from the rear; 5)unplug sensor assembly connect on the main PC board; 6) remove clip that holds the temperature sensor on the compressor output tube ( this is a very strong clip)(also take a small piece of emery cloth and clean the output tube where the clip was attached); 7) use a tapered tool to spread the clip, just removed to, allow the temperature sensor to be removed from the clip; 8) unplug the bucket full switch connector; 9) remove the humidity sensor from the evaporator coil (just a snap-on connection; 10) remove the entire sensor assembly that was just disconnect during steps 1) thru 9) and reinstall the new assembly using the previous steps in reverse order; 11)Plug the unit in and all should be a go!

removed the front cover housing the switch circut board. Removed the defective unit and plugged in the new part. Unit now works fine.

taking apart and testing switch and connections, then searching online and finding the exact problem and part needed
