Why Fanmaster Heater does not run?
- M
  Michael WhitneyAug 13, 2025
  Your Fanmaster Heater might not be running due to several reasons. First, ensure the switch is in the “I” ON position. Check that the plug is properly connected to the power source and the power supply is working. Also, make sure the thermostat is set higher than the ambient temperature. If a temperature sensor override occurred, wait 10 minutes and try starting the heater again. Finally, check if the fuse is damaged and replace it if necessary.

  Jennifer GillAug 16, 2025
  If the motor or pump of your Fanmaster Heater is running but there is no flame, consider these possibilities: * The fuel tank may be empty, so turn the switch to ”O” OFF and refill it. * The ignition device may be dirty, so check and clean the electrodes. * The fuel filter might be blocked, so clean it with clean fuel. * The fuel nozzle could be dirty or blocked; clean it with clean fuel or replace it. * The photocell may be dirty, damaged, or incorrectly installed; clean it with a soft cloth or tissue, and replace it if needed. * The fuel may be dirty, so empty and refill the tank with clean fuel, then empty it again.

What does FO error mean on a Fanmaster HDR20 and how to fix it?
- R
  Robert Morales DVMAug 20, 2025
  The FO error code on your Fanmaster Heater can indicate several issues. It might appear if the ON/OFF switch was in the ON position when the heater was plugged in; in this case, disconnect the plug, turn the switch to the “O” OFF position, reconnect the plug, and switch the heater to the “I” ON position. Other potential causes include no fuel (refill the fuel tank after turning the switch to ”O” OFF), contaminated fuel (empty and refill the fuel tank with clean fuel, and clean the filter), a dirty or damaged photocell (clean it with a soft cloth or tissue), or a dirty or blocked fuel filter (clean it with clean fuel). If it is an ignition error, contact Fanmaster.
