The new thermostat and evaporator fan arrived and I replaced the
thermostat. Compressor kicks on fine. Before all this is had one of
the 2 evaporator fans not running. I ordered a replacement but when the
unit kicked on, neither one of them were running. They should run when
the 2 door contact switches are closed. I checked the voltage when my
meter and when the door switches are closed its getting around 18
volts. Nowhere near 115 it should be. I then went ahead and pulled
both fans and both up with power is directly applied. So, I guess the
motors are fine but first I wonder why one of them was not working and
why now neither of them are? Both motors are wired together then wire
into the freezer but appears one of the leads runs thru a round 2 pole
switch or sensor of some sort mounted up above the right fan near the
evaporator. I wonder if it is some sort of temperature switch. In
looking at the attached wiring diagram, I am thinking it could be the
defrost termination switch. I wonder if the thing has to cool down a
certain amount before the switch closes and powers on the fans? Or
perhaps this switch is bad. I guess I need to see if i can bypass it
and see what happens._______________________________________
