Why won’t my trailer fridge ignite on propane?

1. Identify your fridge type

• If you have a compressor fridge, it does not use propane ignition and this process does not apply.

• If you have an absorption fridge, continue.

2. Switch to propane mode

• Turn the fridge to propane mode.

• This opens the gas valve.

3. Listen for ignition attempts

• You will hear rapid clicking.

• This is the igniter creating a spark at the burner.

• The system may cycle through several ignition attempts.

4. Allow time for gas to reach the burner

• The ignition cycles are designed to give propane time to reach the burner.

5. Flame detection

• A flame sensor is located in the burner area.

• Its job is to confirm whether a flame is lit.

6. Successful ignition

• If the flame lights:

  • The flame sensor detects it

  • It sends a signal to the control board confirming a stable flame

  • The clicking stops

  • Gas continues flowing normally

7. Normal operation

• Once the flame is confirmed, the fridge runs normally.

8. If the fridge does NOT light

•  Possible reasons

  • Air in the propane line

  • Low propane pressure

  • Wind affecting ignition

9. Safety shutdown (lockout)

• If the flame is not detected after several attempts:

  • The control board shuts the gas valve off completely

  • This prevents unburned propane from building up

10. If lockout occurs

• Turn the fridge off

• Wait about 30 seconds for unburnt propane to dissipate

• Try again

11. If it still won’t ignite

• You may need to purge air from the propane line

• Check propane level
