Fridge too cold & Freezer door ?

I'm just about finished with Betty's interior re-hab (I'll post pics soon) and I remembered last year the fridge would get too cold and sometimes freeze stuff. Searching this question I saw mention of moving a clamp on the thermocouple to adjust the temperature but don't see one on mine. I suspect the thermocouple is bad but before getting a new one I thought I'd ask. Also, is there a procedure for rewinding the springs on the freezer door? I took it off to get the gunky seal clean and it un-sprong!

Thanks,

Egad!

ps. the pic is obviously sideways...can't seem to rotate properly

The clamp you're speaking of is a little white plastic clip. I have an extra one from a Dometic fridge if you need it. Just PM me with your address.

Don't fix it too good, then you'll be like the rest of complaining the fridge doesn't get cold enough.

I had the spring do the same thing.

I don't have a PDF instruction sheet, but basically you go through a reverse installation, if that makes any sense.

The clip holds the sensing unit/wire at its highest point in the refrigerator.

When your 'sensing unit', called a thermister goes bad, it depends on how it failed. If it failed in the open position, it will cause the board that operates the cooling unit to run wide open, this creating a potential freezing situation in your fridge section.

If it fails in the closed position, it will do the reverse and essentially turn off the unit causing it to warm up.

The thermister changes it's resistance relative to the internal temp of the fridge and sends that resistance value to the control board, which then either runs the heating section of the cooling unit or shuts it down. There are ways to test your thermister at varying temperatures. Check with your operations manual for details, call the fridge manufacturer tech support line or find a qualified RV tech who is well versed on this subject to do the test.
