Certainly no chances of the ambient temperature getting below 5c over the summer we've had
Have you seen this page from the Waeco/Dometic Coolmatic manual that explains the red light sequences - low (or high?) voltage is just one cause?
Each flash lasts for one quarter of a second. After the series of impulses a pause follows. The sequence for the fault is repeated every four seconds.
Number of flashes - Fault - Possible cause
1 - Line Voltage - The supply voltage is outside of the set range.
2 -Excessive fan current -The fan load on the electronics unit is more than 1 A.
3 - The motor doesn't start - The rotor is jammed 0r The pressure difference in the cooling system is too high (> 5 bar).
4 - Speed too low - If the cooling system is overloaded, the minimum speed of the motor of 1,850 rpm cannot be maintained.
5 - Overheating of the electronics unit - If the cooling system is loaded too heavily or the temperature is set too high, the electronics can overheat.
Constantly - NTC errors - NTC is defective.
