Dual LP/electric refrigerator smell
My Norcold dual fuel refrigerator has an odd odor. The odor fills the unit every few days. First thoughts are either a propane or ammonia leak but the odor doesn't fit either of these distinct scents. It appears when the unit is running on both LP and electric. When I had the LP shut off for a few days during furnace repairs, the odor was not present. Thoughts?

Open the frig outside vent doors and inspect closely for any yellow stains or residue.

I'm not certain that it's ammonia as it smells more metallic.

We had a smell on occasion, especially when driving so the fridge was on lpg. Got so bad I pulled over and found some insulation had fallen into the burner assembly. Pulled the smoldering insulation out with needle nose plyers and checked whole back area for any remaining problems. I believe the good Lord was with us that day. It was a norcold 1200 fridge in a 2003 discovery dp. (The insulation had metal foil backing, hence the metallic odor in our case. Good luck and don’t give up until you find the cause.

This is a 2016 coach. It's had this issue since I bought it in July 2018. It only had this smell every couple weeks. Now it's nearly every day.

SO........
Does fridge cool/function regardless of smell?
YES...then it isn't an ammonia leak cause that would cause cooling unit to overheat and TRIP
Have you inspected the burner/boiler section....is the insulation intact ?
Have you inspected the side wall insulation near boiler/flue stack...is insulation intact?

The unit has been working fine for four months on both AC and LP.

The unit only has the odor when the temperature is around or above 38° F. I've been running it at 32° F for a few days and the odor has disappeared.

I finally had the unit looked at and the culprit was a water leak from the ice maker line which was dripping water into the insulation under the unit. The odor has dispated after a few days of drying. The leak was not apparent as it looked like water from excessive rainfall had pooled. A second look indicated some calcium build up at the connection. It would appear that any water in the refrigerator cabinet indicates a problem.
