A Pössl fridge that no longer cools on any power source usually points to a faulty circuit board or an interrupted power supply.

A Pössl fridge that no longer cools on any power source usually points to a faulty circuit board or an interrupted power supply. First check whether the fridge remains completely silent on 12V, 230V and gas. In Pössl models, Dometic and Thetford fridges are common, and a blocked gas burner or a failing circuit board are known causes. Have a diagnosis carried out before replacing expensive parts.
A fridge that doesn't cool at all rarely points to a single fault. The right approach depends on the type of fridge and the power source you're using.
Pössl has been building campers with absorption refrigerators from Dometic or Thetford for years. These run on 12V (while driving), 230V (on campsites), or gas (off-grid). If your refrigerator stops working, the first question is: which power source is failing? If it doesn't work on any source, there's a good chance the circuit board or the cooling unit itself is faulty. If it still works on one source, the problem is often in that specific circuit.
For a general step-by-step guide to a non-working camper refrigerator, please refer to our comprehensive explanation of refrigerator problems. Below, we focus on typical Pössl points of attention.
Dometic refrigerators in Pössl (such as the RMS 8 series) sometimes suffer from a faulty display board or a loose plug connection. Thetford refrigerators (N3000 series) are known for their sensitive gas ignition. With both brands, a software reset can help: disconnect power completely for 10 minutes and restart.
Repair costs vary widely. A new circuit board costs roughly 250 to 500 euros, a heating element 80 to 150 euros, and cleaning or replacing a gas burner 100 to 250 euros. Labour not included. Always have a diagnosis done first, because blindly replacing parts is expensive.
If the refrigerator is over 10 years old and has multiple faults, a full replacement (1500 to 2500 euros incl. installation) may outweigh the market value of your motorhome. In that case, it is wise to consider all options.
