Scottjeffrey Posted August 14, 2022 Share Posted August 14, 2022 Is the larger hole in the front of the evaporator housing there to cool the bottom of the fan switch? The rear of my fan switch gets very hot. Thinking of putting a micro fan in front of the hole to cool it. Many Thanks, Scott Quote Link to comment Share on other sites More sharing options...
Dudeland Posted August 14, 2022 Share Posted August 14, 2022 If memory serves there is a temperature probe that goes into the case that controls the on/off of the unit. Double check it has been a while. 1 Quote Link to comment Share on other sites More sharing options...

jgerock Posted August 14, 2022 Share Posted August 14, 2022 Upper left hole is larger. Upper right hole accepts brass sleeve with temperature probe. 2 Quote Link to comment Share on other sites More sharing options...
