Thanks for all your suggestions.. To answer some questions, the door seals are fine, the wiring is at least 6mm, the fridge is a Waeco 12/24 volt. It does not have an electric cooling fan, there are vents on the side of the van. And the cooling air supply is not blocked. I will spend time this weekend checking the cycles etc. I am trying to locate a fridgy to check the gas and see if it needs topping up. Thanks again for all your comments, will post again after the weekend with more info on the cycles etc.
This post is helping me with my fridge problem. Indel B 12-24volt compressor fridge using a danfoss BD50F. The compressor is not shutting off at all. Voltage at input is good (over 12.9v) amperage has been dropping all day from 5.68 down to 4.45 fluctuating at the moment. I cant leave my charger off over night as batteries are flat in morning.
We are on power at Richmond at the moment.
The control knob in the fridge compartment goes from 0 to 7. I was informed that this range keeps the compressor running longer the higher the number. I have turned it to 7 overnight and in the morning turned it down slowly expecting compressor to shut down, no such luck. turned down fully to 0 before shutting off.
From what i am reading it appears fridge/freezer 190 ltr (3 years old) needs regassing.
Your thoughts would be appreciated....
