The unit runs but does not heat. In diagnostic mode, I get code F28, which points to either the thermistor or the main control board.
I have troubleshot the machine to within an inch of my life, and I'm down to the last step, checking the resistance on a couple of wires, "If the resistance reading doesn't match the table replace the thermistor. If it does, replace the machine control electronics." Here's where it gets dicey for me, so I need some clarification from more experienced minds.
The chart says:
The temperature in the space is lower than 70, but above 65. The resistance on the multimeter is 16.1 So, is that a match or no? Obviously, I hope the issue is the thermistor; that's $20 as opposed to $160.
And insights? Thanks!
