Thermostat Closed, Fan Does Not Operate - Re-Verber-Ray DX Troubleshooting Manual

1 - Thermostat Closed, Fan Does Not Operate

If the thermostat is closed (on) and heater does not operate, check the following:
1.1
Check the building's main circuit breaker or fuse box. The problem may be a blown fuse or circuit.
1.2
Thermostat Operation: Verify the thermostat is allowing power to be sent to the heater. Confirm by
measuring the voltage to the heater using a volt meter (See picture below). If there is no power, the
problem is in the thermostat and it should be replaced. If power is at the heater, continue on to the
next step.
1.3
Check the electrical connections leading to the fan. Be sure that the wire nuts are tight.
1.4
Using the voltmeter, check to be sure power is going to the fan (pg. 8, pic. 5). If there is power, try
cleaning and oiling (SAE-20 oil) the motor. If fan still not working, it is faulty.
