Had the recall upgrade done in March before a week-long trip. Returned and parked on pad, connected to shore power as usual. Had no reason to check the refrigerator until late May and found it off. Inspection revealed: 1) No 12VDC 2) Thermal Disk installed during upgrade tripped. Reset it. 3) 12VDC came on, lights on refrigerator, audible click from control board. 4) The flue began to warm up. After a few minutes it was quite hot, and the thermal disk tripped again. 12VDC gone. 5) Removed connectors from thermal disk and jumped together for about 10 hours. Flue got hot (normal hot, I don't know...what's "normal"??). Never any cooling in fridge. 6) Pushed *Auto* button off to make unit change to LP. (audible click from solenoid, I presume). After a short time *CHECK* light came on to indicate lack of ignition. Multiple tries had same result. LP odor around burner area - plenty of gas in tank - other appliances work. 7) No odor of ammonia, no "yellow gunk" around. 8) Back to A/C. Audible click from control board when powered. Thermal disk still trips after a short time. No cooling under any conditions. Anyone have any ideas?
