What to do if Dura Heat Heater will not turn-on?

  Andre MackAug 12, 2025
  If your Dura Heat Heater won't turn on and the lamp is off, it could be due to several reasons: the temperature limit safety device may be overheated (in this case, turn the power switch to “OFF” and allow it to cool for about 10 minutes, then turn it back “ON”), there might be no electrical power (check if the heater and extension cords are plugged in and verify the power supply), a blown fuse (replace the safety fuse in the PCB board), or a bad electrical connection between the temperature limit safety device and the PCB board.

  If the fan in your Dura Heat Heater isn't turning on when plugged in and the power switch is in the “ON” position, and the lamp is on or flickering, there are a couple of potential causes. First, the thermostat setting might be too low; try turning the thermostat control knob to a higher setting. Alternatively, there might be a bad electrical connection between the motor and the MAIN PCB assembly.

What to do if Dura Heat DuraHeat DFA-45T will not ignite but motor runs for a short period of time?

  If your Dura Heat Heater won't ignite, but the motor runs briefly and the lamp flickers, several issues could be at play. First, ensure the fuel tank is filled with kerosene. Other potential causes include incorrect pump pressure, carbon deposits on the spark plug, a dirty fuel filter or nozzle, water in the fuel tank, a bad electrical connection between the ignitor and the main PCB assembly, the ignitor wire not being attached to the spark plug, or a defective ignitor. Refill the tank with kerosene if it's empty.

Why Dura Heat Heater ignites but shuts off quickly?

  If your Dura Heat Heater ignites but the main PCB assembly shuts it off shortly after, with the lamp flickering, several factors could be responsible. These include incorrect pump pressure, a dirty air output, air intake, or lint filter, a dirty fuel filter, dirt in the nozzle, a dirty photocell lens, the photocell assembly not being properly installed, a faulty electrical connection between the photocell and the main PCB assembly, or a defective photocell. To resolve this, start by checking the pump pressure.
