Time to tackle the fridge.
I pulled the door off and unhooked propane and the 110v. Then I pulled the screws out that hold it in and slid it out. I moved it outside for a good wash. Cleaned and degreased then sanitized. I brought it into the garage after dry and plugged it in. The rear heater/burner box started to get warm after and hour, perfect. After running the entire night the fridge did not get cold, at all, not perfect. So I tried running it on Propane, but the pilot wouldn’t light. I pulled the burner off and cleaned the rust flakes out of the orfice and reassembled. I was then able to light the pilot, set the temp to coldest and waited 6 hours, nothing again. I read about how you can burp a ammonia filled fridge so I flipped it over for a day, nothing. I read this is due to an anti-rust solvent they mix in the lines with the ammonia/hydrogen/water solution, over time it crystalizes and flipping it over can break free some of the clogs. Next step was to turn the fridge 90 degrees and tap on the lines with a hammer, I repeated this several times, nothing. Then as a last resort I hooked up a palm sander without paper to the lines and used the vibrations to vibrate the crap out of the lines, nothing. I’m almost 100% certain the lines are clogged really bad and this fridge is toast. I’ll set it upside down in a corner until spring.
