Fridge--two problems.
Norcold 1201 LRIM, 2002 Itasca Horizon, so the fridge has got to be pushing 12 years old. We have had it for it for 4 or 5 years. It gets a lot of use; we winter in Mexico and live in it 5 or 6 months there plus a few trips around the Island during the summer.
Today I turned the fridge on (propane) to start it cooling down for a trip in a couple of days.
Started cooling fine. An hour or so later I returned to the rig on another chore and heard a low pitched sound that I thought for a moment might have been a work boat in the bay, then realised that it was coming from inside the rig.
It is a sort of growling or throbbing noise, low in frequency, I would guess maybe 100Hz or so. Not quite pulsing, more throbbing, maybe a couple of times a second.
It is coming from the fridge, nearer the top than the bottom. When I open the fridge door the fans (normal sound) stop as does the throbbing sound. Fridge is still cooling well.
Outside, removing the panel I can still hear it but it is louder inside.
While outside looking in from the outside I noticed more rust than I would like to see on the cooling unit. I later returned with the camera to take some photos of it.
While doing so, the throbbing noise stopped! Fridge burner was still running, I went inside and there was no fan noise from the fridge either. I opened the fridge door and the light came on. I could still hear the gas burner.
Took the pics and left.
I'll have to come back to post those: DW says dinner is ready and we have two always hungry dogs so I better go while dinner is still there to enjoy!
Happier now: Coho Salmon steak in fennel and a touch of lime, peppers, beans and quinoa and a nice if I do say so myself home made Pinot Gris. The dogs got a bit of salmon skin.
So Problem # 1. Any thoughts from the description? I suppose I should be able to record and post an audio file but that is far beyond me!
Problem, or really question, # 2:
What are the thoughts of this cooling unit.
And taking it all together, what now?
