TC has to be level if using gas ref . If using AC voltage not so much...still not excessively off level. Otherwise the ref will lock out after three resets and will need to be reset by a dealer . That means many $$$ unless you know someone on line who can assist you as happened to us . We were in the mountains of Va and our ref was on gas and way out of level . Luckily some one on line assisted us by tell us how to reset the circuit board. We leveled the TC after that.
The fridge doesn't care what the heat source is. It needs to be close to level on gas or AC. The reason is the coolant circulates by gravity through a spiral tube set. It can't flow uphill.
