What to do if Pinnacle Climate Technologies Heater won't start and shows E1?
- SStephen FrancoAug 4, 2025
If your Pinnacle Climate Technologies Heater won't operate, or the motor runs briefly with the lamp flickering and the LED display showing “E1”, there are several potential causes. Start by filling the tank with fresh kerosene if it's empty. Then, adjust the pump pressure if it's incorrect. Next, clean or replace the spark plug if it's corroded or has an incorrect gap. Also, clean or replace the fuel filter if it's dirty, as well as the nozzle. If there's moisture in the fuel tank, rinse it with clean, fresh kerosene. Inspect all electrical connections between the transformer and circuit board. Re-attach the ignitor wire to the spark plug if it's disconnected. Finally, replace the ignitor if it's defective, and adjust the rotor if the spacing is improper.
