Overview
RV refrigerators fall into two main categories: absorption refrigerators, which run on 120V AC power or LP gas and use a heat-driven cooling process, and residential-style refrigerators, which run on 120V AC power and use a conventional compressor. Each type has its own common failure patterns.
In Central Texas, RV refrigerators work under significant thermal stress. Summer ambient temperatures regularly exceed 100°F, and rooftop ventilation that is inadequate or blocked by debris forces absorption units to work against heat loads they were not designed to overcome. Many no-cooling complaints on absorption units in Texas trace back to ventilation conditions rather than a failed component — but a ventilation-related cooling failure can also mask a component issue that has been developing.
Boss Bull services Dometic, Norcold, and Furrion refrigerators — the three most common brands in the RV market. We address cooling concerns, control board failures, LP ignition issues, and ventilation problems during on-site mobile service visits.
Voltage diagnostic at the refrigerator circuit during a no-cooling service visit. Confirming voltage at the unit is one of the first steps when the refrigerator is not responding on AC power.
Voltage is verified at the refrigerator before assuming a component fault — a low or absent supply voltage at the unit is a common cause of no-cooling presentations, particularly on residential-style units that require full 120V for the compressor to start.
Common Problems We Fix
- Refrigerator not cooling or not maintaining temperature
- Freezer compartment cooling but refrigerator section warm
- Unit cycling off prematurely on LP or AC power
- Refrigerator working on one power source but not the other
- Error code displayed on the control panel
- Ammonia smell near the rear of the refrigerator or at the exterior vent
- Refrigerator running constantly without reaching set temperature
- Interior light on but no cooling function
Exterior vent access during a no-cooling diagnostic. The cooling fins, burner assembly, and vent path are inspected before component replacement decisions are made.
Vent blockage and burner condition are evaluated at the exterior access point before the interior is opened. Restricted convective airflow at the exterior vent is one of the most common contributing factors to absorption refrigerator cooling loss in Central Texas summer heat.
Common Findings During RV Refrigerator Repair Service Calls
No-cooling complaints on RV refrigerators in Central Texas follow recognizable patterns by brand and unit type. The following conditions appear most frequently.
- Dometic control board failure — produces error codes or no-cooling on LP and AC with the cooling unit intact
- Norcold control board or power board failure — similar presentation to Dometic board failures
- Roof vent blockage or failed roof vent cover reducing convective airflow across the cooling fins
- Cooling unit failure on older absorption units — ammonia odor, yellow residue at the vent, or loss of cooling on both LP and AC with no error code
- LP burner orifice fouling or igniter failure causing LP operation failure
- Low voltage or poor power supply connection affecting residential-style compressor startup
- Door gasket damage or deformation allowing warm air infiltration
Technician Observations
What Owners Commonly Report
Presenting complaints we hear most often on these service calls.
- My refrigerator stopped cooling and I have food that is going to spoil
- The freezer is cold but the refrigerator compartment is warm
- My fridge works on LP but not on AC, or vice versa
- There is an error code on the display and I cannot clear it
- I smell something near the back of the fridge that might be ammonia
What We Frequently Find
Actual conditions we document when we arrive on site.
- Control board failures on Dometic and Norcold absorption units — the control board is the most common single-component failure and produces no-cooling or error-code presentations
- Ventilation blockage at the exterior roof vent — insect nesting material, debris accumulation, and damaged vent covers restrict airflow and cause cooling efficiency loss under Texas summer heat loads
- Cooling unit failures on older absorption refrigerators — the sealed ammonia-absorption circuit fails and produces an ammonia odor or visible yellow residue at the exterior vent
- LP ignition failures — dirty burner orifices, clogged pilot pathways, or failed igniter components prevent the absorption unit from running on gas
- Voltage-related failures on residential-style units — low shore power voltage or inverter supply issues that prevent the compressor from starting
- Door seal failures that allow warm air infiltration and cause the unit to run continuously without reaching temperature
Service Recommendations
What we typically advise based on our findings.
- If you smell ammonia near the refrigerator, do not continue operating the unit — ventilate the RV and schedule a service visit promptly
- Roof vent condition matters for absorption refrigerator performance — restricted ventilation is the most common cause of heat-related cooling loss and is often addressed before component replacement
- Residential-style refrigerators require consistent 120V AC power at adequate voltage — a long shore power cord run or poor connection can contribute to refrigerator performance problems
- A maintenance visit addressing ventilation, door seals, and burner condition may restore performance before a component replacement is needed
