Troubleshooting Chart

Problem
1. Incorrect supply voltage.
2. Overloaded circuit.
3. A short circuit exists in the supply
or heater wiring.
4. Defective circuit breaker.
1. Insufficient element temperature.
2. Incorrect supply voltage.
3. Element has failed.
4. Thermostat knob is not turned
clockwise far enough to activate heater.
1. Heat loss from room is greater than
heater capacity.
2. Defective thermostat.
1. Dust, lint or other matter has
accumulated inside heater.
1. Defective motor or internal connection.
2. Fan or motor jammed.
1. Thermostat set too low.
2. Heater has tripped the high-
temperature reset switch.
3. Power not on at the circuit breaker.
4. Broken or poorly connected
wire(s) to heater.
5. Defective thermostat.
Solution
1. Verify that supply voltage matches the heater rating.
2. The total amperage of all heaters on a branch circuit must not be more
than 80% of the amperage rating of the circuit breaker and supply wire
ratings. Use a lower wattage heater, or reduce the number of heaters
on the circuit.
3. Shorted supply or heater wires may be accompanied by severe sparking.
Inspect all supply and heater wiring insulation for damage. Do not reset
the circuit breaker until all electrical shorts have been repaired.
4. Replace the circuit breaker.
1. Allow a few moments for element to reach operating temperature.
2. Verify that supply voltage matches the heater rating.
3. Replace element.
4. Turn up thermostat.
1. Close doors and windows. Provide additional insulation, install a
higher-wattage heater or multiple heaters if necessary.
2. Adjust thermostat to its lowest setting. If heater continues to run
(allow two minutes for the thermostat to respond) and room temperature
is greater than 50 degrees, replace thermostat.
1. Clean heater (see "Operation & Maintenance" section for instructions).
1. Heater or fan motor requires replacement.
2. Remove obstruction and press heater reset button (after allowing the unit
to cool). Test heater operation--if reset button has been pressed (be sure
to listen and feel for a click indicating it has been reset), but heater does
not run, heater requires repair or replacement.
1. Adjust thermostat to a higher temperature until heater operates.
2. Press the heater reset limit control (see "Operation & Maintenance"
section for instructions).
3. Turn on the correct circuit breaker in the main panel.
4. Turn off power at circuit breaker. Check supply wire continuity and
proper connection to heater wires.
5. The entire heater, or any of its components may be checked for
continuity to determine the cause of any problem. Repair or replace
the heater.
