A defective Thermister will still TEST OK
A Dirty flue will not cause a 120 side problem
If the unit operates LP and 120 the board is OK
The fact that adding a fan is very strange since it decreases cooling. That will NEVER happen. Are you positive the roof top ventilation is NOT blocked?
As long as roof top ventilation is clear, the BEST test is to hot wire the 120 element for 24 hours(the 120 element is good). After 24 hours if the refer is NOT below 38 degrees, the CU is defective. Doug
