Waco Fridge Bavaria 37

[Scorcher IV]

Has anyone replaced the thermostat controller in one of the above fridges, mine runs for a short time then stops fiddle with the switch and it starts again. Where would be the best place to get a replacement switch.

These people are very helpful.

Look at the parts lists and then send them an enquiry with the part number, and they will ping you back the cost.

If it's the standard fridge apparently thermostat failure is a common fault. I replaced ours with one of these

Works a treat

That would be my preference as well (but while my old thermostat still works fine, I just carry the SODIAL unit as spare).

Thanks for the information, where did you fit the Social unit? and does it have the four contacts that the normal switch has?

I fitted it down next to the compressor and drilled a hole for the sensor to sit just inside the top of the fridge. From memory my thermostat only had two wires, basically an on off switch so just ran the same wires to the new thermostat.

I'm also going out to the boat next week with a few mods including a variable resistor which can be used to control the speed of the compressor (fast when engine running, slow when sailing) as well as a load of PC fans & controllers to manage the air flow better around the compressor and condensor.

How do you tell whet speed the compressor is running at?

[jonrarit]

According to the Danfoss instruction sheet if no resistor is fitted, the unit will default to 2000rpm but a variable resistor in the control circuit can speed up the compressor to a maximum of 3500rpm - see attached

Sorry what I meant was, how are you going to be able to tell what speed it is running at using a variable resistor and not a fixed one.
Thought you might of had a cool way of seeing it!

[jonrarit]

Ah ..... the resistor I'm planning on using looks for all purpose like a "volume" control

[Nigel]

Surely an ignition operated relay with a fixed resistor would do the job?

Ultimately yes Nigel but just want to play around with it manually to see if i can find an "optimum" .......and don't call me surely

Sounds like my fridge thermostat but I consider normal as their is a large gap between the on and off positions (the technical term called hysterics )

  Or perhaps hysteresis.
