Questions:
Does fridge defend indicate Overheating on GAS only
OR does it also show overheating when using Electric?
*Both heat sources do same thing...provide heat to boil the ammonia into a vapor
Overheating can be due to:
Low Propane System Pressure
Dirty burner/orifice
Faulty Electric Heater Element
Cooling UNIT blockage OR a LEAK
Does fridge not get below 50*F on gas, on electric or both?
What temp is freezer?
Have you checked the food compartment drip tray drain tube?
Broken/cracked or bug plug missing warm air can be drawn in making food compartment warmup
Door seals......have you checked them?
Ventilation, draft ad/or inadequate heat generates insufficient quantity of ammonia vapor needed to absorb heat from Both freezer & food compartment
Questions/Clarifications:
50*F.....that is temp in food compartment Correct?
Freezer temps?
Better on Gas vs Electric....how much better?
Works great if below 90*F Ambient air temp.......that suggests Draft/Airflow, Dead air space, warm air being drawn into food compartment (drain line/door seals etc), inadequate heat transfer (overheating due to lack of coolant flow) AND/OR Combination of above.

We believe that RVing should be fun, spending time trying to fix stuff is frustrating
There is a pattern on iRV2, and that pattern is that folks do not seem to know how to use the troubleshooting functions of the Fridge Defend.
In the quoted posts, these are very good questions.
It could be that after a number of posts the problem may be fixed?
It is clear that the owner of this fridge is frustrated when they state that they are on a schedule, and their fridge is not cooling.
Let's start with some facts:
- The fridge boiler is responsible for running the entire refrigeration process
.
- The refrigerant is the only thing that cools the boiler if one does not have a Fridge Defend
.
- The Fridge Defend stores Diagnostic and Error Codes for troubleshooting.
With these facts, in the time it takes to make breakfast, one can diagnose their problem if they have the Fridge Defend.
Simply put the control into the setup mode by following the instructions.
Send us the diagnostic variables, and we can tell you the following:
- How many times the Fridge Defend has displayed an error code.
- If there is a problem with the cooling unit producing refrigerant.
- If there is a problem with wiring to the fridge.
The above is a summary of the
troubleshooting capabilities using the Fridge Defend.
This takes the guess work out of diagnostics by giving data that is used to make intelligent repairs. We have posted on our website videos and provide written instructions on how to use the Fridge Defend to solve your cooling issues.
Hope this helps fellow RV'ers do what they like best, we are here to help
