Dometic B2200 available for spares.

[Jake Royd]

My B2200 has bitten the dust.
It is showing a single red flash on the indicator panel which in the manual means the interior temperature probe has failed.
I replaced it to no avail I'm afraid.
I've hopefully sold a couple of loose bits and have 'the rest' available for spares.
You may want the whole thing?
I have removed and reconnected the PCB incase of some joint corrosion, made no difference.
Things like the evaporator fans and air circulation fans are removable as is the PCB.
The cooling circuit works perfectly (compressor, evaporator and radiator etc.) not sure if the whole thing is removable as a system as I write.
The interior frame, filters , led lights etc. is all available.
It's located in Malvern.
Let me know if you have any interest.

Why not strip all the controls off it and fit a standard controller?

It will switch 10 amps and cost about £13. You've got nothing to lose

I'm pretty handy but I don't think I would do this. Possibly with clear details I could.
I have already ordered a Maxxairfan to replace it and that I think will be superior in most respects apart from when it's baking hot. It can also run on 12v when there's no EHU.
Time will tell

Should be easy to do, this diagram comes with the controller...

So wire it up like this...

You'll need a 20a rocker switch to switch the fans off, the controller has it's own off switch so you can have fan only mode.

The indoor fan might have multiple wires for different speeds so find the low or medium one probably best.

Also needs to be a single speed compressor. The house ACs nowadays are 3 phase mosfet driven variable speed computerised things but I don't think these are.

Posted in your other discussion as I had not seen this at that point. But as per that post I need a replacement recirculation fan, well I think it’s the fan. I got electrical burning smell from it. On one fan speed. Strangely it’s been okay since.
Could be the fan speed controller of course…..everything else is good.

Sorry you did not pick this up earlier Wingphil you would have been welcome to have parts or the whole thing.
Apologies it's gone now.
I did observe whilst trying to fix mine that the fan connections appear to go direct to the PCB so I would assume speed control is on the board.

Thinking about it , Wingphil I tried on mine removing and refitting the PCB incase there was corrosion affecting a connection.
Your description of burning and then seeming ok might suggest you have a problem like this.
It might be worth unclipping and inspecting and reconnecting the PCB.
This is relatively easy to do.
Be a little careful, there are capacitors on the board.
