1. Understand what the clicking is

• The clicking sound comes from the igniter inside propane appliances (fridge, furnace, water heater).

• It means the system is trying to light or relight the propane flame.
  
  

2. Know what triggers it

• Your appliance constantly monitors whether a flame is present.

• If the flame goes out (for example):

  • Strong wind blows it out

  • Low propane pressure

  • Air gets into the propane line (like after a tank change)
    
    

3. What the system does automatically

• The control board detects the missing flame.

• It automatically starts an ignition cycle.

• You’ll hear clicking as it tries to relight the flame.

• It may try several times in a row.
  
  

4. What happens if it works

• If the flame relights successfully:

  • The clicking stops

  • The appliance continues working normally

  • You may not even notice there was an issue
    
    

5. What happens if it doesn’t work

• If it cannot relight after several attempts:

  • The system goes into safety lockout

  • This stops propane from flowing to prevent unsafe buildup
    
    

6. When you should check things manually

• Pay attention if:

  • Clicking continues for more than 1–2 minutes

  • The appliance keeps shutting down or locking out

• Possible causes to check:

  • Low propane levels

  • Blocked vent

  • Air in the propane line (especially after changing tanks)
    
    

7. Key takeaway

• Short bursts of clicking = normal self-restarting system

• Continuous clicking or lockout = time to troubleshoot
