An RV refrigerator that quits working is one of those problems that feels small until you're three days into a trip to Lake Lanier with a cooler full of melted ice and spoiled food. These absorption fridges run on a different principle than a home refrigerator, and diagnosing them wrong - or working on one without the right training - can turn a fixable problem into a dead cooling unit or worse, a boiler tube leak.
Tristan is certified on both Norcold and Dometic refrigerators, the two brands that show up in the overwhelming majority of RVs on the road today, and he treats them as the different systems they actually are rather than applying one generic fix to both. Whether the unit is stuck on gas mode, throwing an error code on the display, or just not getting cold no matter what setting it's on, he can pull the panel and diagnose it at your rig.
This is one of the repairs where being mobile really matters - a fridge that's failed while a trailer is parked at a campground near Stone Mountain or sitting in storage isn't going anywhere, so the technician has to come to it.
Signs you need fridge repair
- Refrigerator won't cool on gas, electric, or both
- Yellow, sooty flame or burnt smell near the fridge's outside vent
- Ammonia smell, which can indicate a boiler tube leak and should not be ignored
- Error code or blinking light on the fridge's control panel
- Fridge cools intermittently or takes far longer than it used to
- Cooling fins on the back cooling unit show yellow staining
- Fridge won't switch between gas and electric modes properly
What Tristan does
Control board & thermistor diagnosis
Many modern Norcold and Dometic units rely on a control board and thermistor to manage temperature and mode switching. Tristan checks these first when a fridge isn't cooling evenly or is throwing an error code, since board and sensor issues are common and don't always mean the cooling unit itself has failed.
Gas system & burner service
On gas mode failures, he checks the burner assembly, orifice and gas valve for soot buildup, blockage or ignition issues, since a dirty or misadjusted burner is a frequent cause of poor cooling that gets mistaken for a dead cooling unit.
Cooling unit evaluation
If the ammonia-based cooling unit itself shows yellow staining on the fins or an ammonia smell, that's a sign the boiler tube may be leaking or the unit is failing. Tristan evaluates whether replacement of the cooling unit is warranted versus a more straightforward electrical or gas fix.
Ventilation & installation check
Poor airflow behind the fridge is a common, easily overlooked cause of weak cooling, especially in units that have been reinstalled or had cabinetry modified. He checks vent clearance and fan operation as part of the diagnosis.
Why mobile beats hauling it to a dealer
A refrigerator that's failed doesn't strand you the way a dead engine would, but it does mean food loss and a ruined trip if it's not addressed quickly - and a full trailer refrigerator isn't something most people want to haul to a shop and leave for a week. Tristan comes to the rig wherever it's parked, brings his Norcold and Dometic certified diagnostic approach with him, and works through it right there.
It also matters for rigs sitting in storage between trips around Oakwood or Clermont - a fridge issue found before a trip, rather than during one, is a much easier problem to fix on a normal schedule instead of scrambling mid-vacation.

Questions we get asked
- Is it safe to keep running the fridge if I smell ammonia?
- No - an ammonia smell can mean the boiler tube in the cooling unit is leaking. It's best to shut the fridge down and have it looked at rather than continuing to run it.
- Can a cooling unit be repaired, or does it need full replacement?
- It depends on what's actually wrong. Some cooling issues trace back to the control board, thermistor or burner rather than the sealed ammonia system itself, so Tristan diagnoses before assuming the whole cooling unit needs replacing.
- Do you work on both Norcold and Dometic units?
- Yes, he holds certifications from both manufacturers and treats them as the distinct systems they are rather than a one-size-fits-all repair.
- My fridge only cools on electric, not gas - what causes that?
- That's commonly a burner, gas valve, or ignition issue rather than a failed cooling unit, and it's one of the more straightforward things to diagnose on site.
