I'm having an issue with the emergency drip pan filling, tripping the safety shut-down switch. I've cleaned the drain pipe which is clear, but the pan still fills. It takes a day or 2, but still fills.
The question is..Is there something inside of the unit, under the coils maybe, that needs attention? Is it ok to turn off the air, cut the silver tape, remove the panel and look? Also, while I'm in there, should I clean out the coils\coil area and how?
Help.
