What to do if my HeatStar Gas Heater has no spark?
If your HeatStar Gas Heater has no spark, consider the following: * Check the length and gauge of the extension cord for proper amperage draw. Refer to the requirements on page 4. * Verify the wiring to the igniter using the wiring schematic in the manual. * Inspect the gap between the electrode probes, ensuring it is between 2.3 - 3 mm. * If there is still no spark, replace the igniter assembly. * Replace the oil flame control assembly.
What to do if my HeatStar Gas Heater motor overheats?
If your HeatStar Gas Heater's motor overheats or stops, here are some steps to take: * If the motor speed is too low (it should operate at 3450rpm), replace the motor. * With the heater disconnected from the AC source, rotate the fan clockwise to make sure the motor is free. * Remove the air filter housing from the motor and check the pump rotor for damage. If it's damaged, replace the rotor assembly. * If the wiring is correct, the pump rotor is okay, and the motor isn't rotating freely, replace the motor or power-pack assembly. * Replace the oil flame control assembly.
