Thermo King RMN II

[simonh]

Hi

I have an old railway refrigerated container with a Thermo King RMN II on it I am looking for a workshop manual for this if any one can help that would be great, it has a Therm Guard V controller.

The main issue I am having is that it seems to be stuck in sort of a limp home mode the fridge wont go any colder than zero degrees Celsius even though it is set on -20. when I have it running on the diesel engine the engine does not get above an idle??

Any thoughts or ideas would be great

I have attached a photo of the unit for you to see

What's the gas pressures when it's running it's not something simple like the speed solenoid seized

Am thinking its electrical as it was working fine till I had an electrician come and work on it the other day, but will check gas pressures when its running and will let you know

When it's on mains electric how does it perform? and did it perform better before the electrician cursed it.
