RV Refer Cooling Improvements - Part 1
This is an attempt to rectify a less than professional RV refer install by the manufacturer. My RV temps were getting into the high 40s and 50s when ambient temps reached 100+F. After doing some r...

Thermostat will not turn fans on because the thermostat is suppose to be installed on condenser fin *far right one*.
It measures FIN temp and turns fan(s) on/off based on condenser temp-----NOT ambient air temp
Fans should be mounted above and OVER absorber tubes (not out if open space by tubes)
The idea is to pull air in thru lower vent....have it flow THRU absorber tubes and the discharge out top THRU condenser fins
Current fan position is not pulling air THRU the absorber tubing
Food section temp of 39*F with outside temp at 91*F is acceptable.
Fridge thermostat operates 'cooling cycle' based on 'fin temp' in food section compartment ----thermistor on far right fin senses fin temp.
Freezer section temp is NOT sensed or used to control cooling cycle.....it just is 1st in process.
If already cold less heat is transferred to coolant and more heat absorption is available in food section.
What temp setting are you using?
If you do not have an adjustable temp control o upper panel then thermistor can be moved to affect fin sensing for thermostat control.
Move clip UP for colder temp
Move clip DOWN for warmer temp
Moving thermsitor will affect overall temp by 4*F-6*F
