Hello,
I have the Alpine 3700fl with the 2118 unit installed. Never has really worked properly. Freezer about 15-20 degrees and fridge 40-50 degrees.
Troubleshooting thus far:
1. Thermistor checked out fine
2. Each heating element is working and drawing 2.5 amps when on
3. Door seals and flapper function properly
4. Fans cycle on and off as it is in a slide when commanded by the condenser thermostat
5. I have added an additional fan on top of condenser and one on the bottom of absorber coils to help move more air with little yield.
6. Unit is level according to the requirement.
7. I did notice around the fins in the fresh food section that there is a gap where one can see the the evaporative coil and insulation. I dont have another to see if that is a design flaw or purposely manufactured as such.
8. No error codes logged in the diagnostic menu and the fin temperature seems to be accurate compared to temp gun and thermometer.
Does anyone have a service manual?
Dealer is no help and neither is Norcold.
