Dometic rm2652 igniter

On my previous trailer the electrodes lasted about two years. Then they wouldn't spark on cool damp mornings. I finally got to the point of carrying a spare.

Since many people don't have that much trouble with them I always wondered why mine needed so much attention. One theory I had was something about the installation caused numerous restrikes when moving-due to airflow and wind.

Those igniters are very reliable- try pulling the spark lead off the igniter and hold it about a 1/4 inch from the terminal (carefully, with insulated pliers), you can also just pull the lead and listen for it snap. If it sparks then the spark probe is shorted (very common). Remove the spark probe, lightly sand the metal tip, wipe the ceramic down with silicone spray lube and reinstall at the correct gap. Dollars to donuts that will fix it.

The spark electrode ignites main flame......when fridge temp is reached main flame goes off. Then when fridge temp drops spark electrode reignites main flame again.

Are you going to stand around check fridge temps and relighting main flame as needed ?

Spark gap shuld be 3/16" between tip of electrode and burner
