Checking the fan motor thermostat
➢
NOTE:
On late model, Blaze construction heaters, the circulating fan motors are
equipped with a thermal heat thermostat that is not serviceable.
➢
The motor thermostat is wired in series with the 120-volt limit and temperature controller
circuit.
Check to ensure the thermal heat thermostat contact is closed
by testing for continuity, using
the 2 white or 2 grey wires leading to the circulating fan motor.
•
If the contact is closed, the thermal heat switch is good.
✓
If the contact is open, the ‘Circulating Fan Motor’ is defective and needs to be replaced.
