Propane gas leak?

We have had an intermittent propane smell in our kitchen area over the last week. It has happened with the windows open and closed. Very strong odor. Nothing on at the time except the refrigerator operating off of propane. Checked the stove, water heater and furnace. All were off. Shut off the main propane tank valve and odor goes away. Very random occurrence (3 times in five days). Carbon monoxide alarm not alarming but smell is very concerning. We have been turning the main gas valve off at night as we are uneasy to sleep with it on until we figure it out. Could this be the refrigerator? Does anyone have any suggestions? Thank you!

Dometic has a recall on some propane cooktops and stoves that may leak when not in use and with all burners turned off, Here is info -- need to check if your stove is included. If so you need to turn off propane at the tank until repaired/

We have a Furion cook stove and a Dometic refrigerator. Are they the same company?

First... a propane leak can be VERY dangerous!! If the smell of mercaptan (additive... propane is odorless) is strong like you describe, I would suspect in this order: stove, refrigerator, furnace, hot water tank. If it's strong, I would suspect inside the rig. If it's a fitting/hose under the rig, you will readily smell it underneath... provided no wind. Propane sinks.

Leaks at fittings are fairly easy to find using soapy water. Pop the stove top off and find the propane hose connection... usually in the back area. Spray all fittings with soapy water and watch closely with a flashlight. It will bubble visibly if the fitting is leaking.

Same for the refrigerator. Take off the exterior vent panel and check the fittings.

Word of advice:
Look underneath your motorhome for a small aluminum "manifold" that has one propane hose going in, and several coming out - this distributes low pressure propane to your appliances. It's usually located close to where your stove & refrigerator are. Now notice the threads on those hoses have an orange color. That is a high strength, dual purpose thread locker/sealer. Some mistake this for red Loctite - which it IS NOT! It's usually Permatex Orange thread locker - which is removeable. BUT... it takes a LOT of HARD twisting. This is by design - you don't want propane hoses vibrating loose in your rolling earthquake motorhome.

If (or when) you find your leak, use that orange sealer/thread locker - NOT yellow Teflon tape or gas pipe dope. Those are NOT designed for RV use.

If you can't find the leak and still smell it... I strongly recommend getting a professional to fix it. Not something to mess around with!

Did not have their unit for a year even.

I hope they are disclosing that their RV for sale has a propane leak, if it still does.

In viewing the ad
A Lithium Ion battery upgrade with 3,000 watt inverter & large solar array. Also, dual ACs with soft start in a 29 footer.

Those are some bad-ass/expensive upgrades.

But the asking price probably will not gain much attention.
