Refrigerator runs on A/C but not LP

[zell66]

I have a Dometic unit and it runs perfectly on A/C but refuses to ignite on LP. According to manual I have tried restarting fridge 3 to 4 times but nothing. Yes LP tank is full. lol

Any Ideas???

Good to hear it. Thanks for coming back and letting us know.

Take a table knife. one that a magnet will stick to and hold it flat side near the coil (like 1/8" away) and see if it's attracted to teh coil the coil on the gas valve that is.. May be an open coil bad valve. clogged burner orifice.

I have had to try lighting my Dometic fridge multiple times on occasion. The worse time for me was when FIL borrowed both my tanks. It took MANY attempts to get it to light even after the stove, furnace and WH were going strong.

Spark may be going to ground. Clean the igniter and try again.

Did that. Nothing. I hear the clicking coming from circuit board area and not probe end.

When you turn on the furnace does the blower start running?

Ava has a good point!

I fired up the furnace for the fist time of the season and it would not ignite.

A rather large sliver of rust had dropped out of the burner tube and rested between the burner and sence/ignitor probes thus grounding them out. You could not even hear the ignitor clicking. Just a red fault light and a running blower.

Blew out the rust sliver and all back to normal.

My older fridge will stop on occasion and a quick blow on the burner to remove any rusted bits from the heating tube always cures it.

Check light is triggered when flame fails to light/fails to PROVE it lit

1st thing...
remove burner/orifice and clean them
Soak the orifice in alcohol and then blow it out (LOW air pressure---NO poking ANYTHING thru orifice ---you will damage it)

Often debris/bugs even spider webs collect during periods of non-use so burner cleaning is 1st thing to do when not lighting off (furnace/water heater etc)

If spark electrode is NOT making a spark then you need to do more investigating/testing

Posting the MODEL of your fridge would be helpful for specific info

Is gas actually getting to the fridge?

x2. do the stove burners light? is the main LP supply on?

All 3 burners are lit and going strong.

Also, the fridge still needs 12V DC to run when set for LP.
