A weak or intermittent flame typically signals burner blockages or component failures. I always recommend cleaning the burner assembly, checking for debris, and measuring electrical connections.
Precision matters when ensuring your refrigerator delivers reliable cooling, even during long summer road trips.
When Your Fridge Isn’t Cooling
Your RV refrigerator’s cooling performance hinges on three critical factors: door seal integrity, proper RV leveling, and maintaining clear airflow around vents.
I’ve seen countless cooling issues stem from these often-overlooked areas, where a simple door gasket replacement, careful parking technique, or vent clearance can restore your fridge’s chill. Let me walk you through how to tackle these common cooling challenges and keep your food fresh on the road.
Door seal problems
When a door seal fails, your RV refrigerator’s cooling efficiency can plummet faster than ice melting on a summer dashboard.
Identifying and fixing seal problems is crucial for keeping your food cold on long trips. Here’s what to watch for:
- Check the gasket for cracks or gaps using the dollar-bill test
- Clean the seal with mild soap and water
- Inspect door alignment and tighten hinge bolts

Replacing a worn gasket is cheap insurance against warm drinks and spoiled food during your adventures.
Leveling your RV
Gravity’s silent sabotage can turn your RV refrigerator from a cool sanctuary into a lukewarm disappointment.
Absorption fridges demand precise leveling—within 3 degrees—to keep your food cold.
A simple carpenter’s level becomes your best friend, checking side-to-side and front-to-back alignment.
When temperatures climb, stabilize your rig using jacks, wheel chocks, or a leveling ramp.
Center that bubble precisely.
Then, patience is key: allow 6–12 hours for the cooling cycle to restart.
Helpful hint: use a quality thermometer to monitor refrigerator temps (32–37°F) and freezer performance.
Frequent driving can disrupt internal circulation, so re-level and run a full cooling cycle to restore efficiency.
Airflow and vents
In the world of RV refrigeration, airflow isn’t just a detail—it’s the lifeline of cooling efficiency. Proper ventilation can make or break your fridge’s performance. Here’s what you need to know:
- Keep rear vents clear with 2–3 inches of unobstructed space
