What usually fails
Most RVs use gas-absorption refrigerators (Norcold and Dometic) that cool using heat — from a propane flame or an electric element — instead of a compressor. Typical failures:
- Heating element or burner failure — works on one power source but not the other is the classic clue.
- Control board faults — blinking fault codes, refusal to light, or switching modes on its own.
- Thermistor failure — fridge freezes everything or never gets cold enough, because it can't read its own temperature.
- Blocked or aging cooling unit — the sealed ammonia system; yellow residue or a strong ammonia smell near the back of the fridge is a serious warning sign.
- Ventilation problems — roof vent or side vent blocked by nests or debris, especially after storage, starving the unit of airflow.
- Door seals and alignment — warm air leaks that make a healthy fridge look broken in summer heat.
Symptoms worth calling about
- Fridge warm on electric, cold on propane (or the reverse)
- Freezer cold but fresh-food section warm
- Fault lights or codes on the eyebrow panel
- Burner clicks repeatedly but won't stay lit
- Ammonia or chemical smell — stop using the fridge and call; this one is safety-relevant
- Fridge died after storage, a move, or sitting unlevel
What a mobile tech can and can't do on site
On site: power-source testing (element, burner, igniter, gas pressure), control board and thermistor diagnosis and replacement, vent clearing, seal and latch work, and honest assessment of the cooling unit. If the cooling unit has failed, replacement cooling units can often be installed without removing the fridge from the RV.
Honest limits: a failed sealed cooling unit on an older fridge can cost a meaningful share of a new fridge — a good tech will lay out repair-vs-replace math instead of defaulting to the bigger ticket. Full fridge replacement in tight interiors occasionally requires removing a window or door, which can turn a mobile job into a shop job.
Have this ready when you call
- Fridge brand/model (label is inside the door frame) and any fault code showing
- Does it cool on electric? On propane? Neither?
- How level is the RV parked, and how long has it been sitting?
- Any smells near the fridge, inside or at the outside vent
- RV year/make/model and where it's parked
