Hi I have a coachman with a thretford fridge when it's hooked up on site we get a spanner symbol and blue flashing light, when switched to battery fault 10, switch to electric fault 12 and gas fault 12 any ideas as the summer is on its way
Fault code 12 indicates that the voltage supply to the fridge is outside the operating range of between 9.5 and 15 volts DC. The fact that the blue light flashes on and off would indicate that there is a poor connection at one of the wiring joints
I expect you’ll find the solution in your handbook as Monty15 suggests.
We also get a blue flashing spanner, happens when we’re stopped for lunch. Our fridge is set on A (automatic), as we use EHU on site. It runs off the leisure battery when the engine is running & we keep the gas turned off. It’s telling us that there’s nothing cooling the fridge while the engine's not running & we’re not hooked up.
