PCB THERMISTOR SHORTED (On Convection Models)

Cause

The PCB Thermistor is Shorted, this could also indicate a bad Main PCB.

Solution

Check the thermistor resistance and voltage from Main PCB.

DETAILS BELOW:

Thermistor Shorted

Example from Model LMV201 

If Thermistor is shorted you will read less than 1 ohm

Thermistor Shorted

Example from Model LMV201 

If Thermistor is Shorted you will read no or minimal voltage. To confirm Main PCB is good remove thermistor at board connector and confirm 5Vdc is coming from Main board.
