Subject: Bypassing a fridge thermostat?
I have a industrial type SS fridge.
I think this can either be a fridge or a freezer, but the thermostat is
the limit.

I am currently running a Johnson digital control on it.
I would like to bypass the internal thermostat and have it turn off and
on based on the johnson control.

Can I just jumper the thermostat? Or is this more complex?

No need to bypass or jumper the thermostat at all. Just turn the fridge
to its lowest setting and plug it in to the Johnson control. The
Johnson unit will keep it an any temp you want that is at or above the
minimum temp the internal thermostat will keep the fridge.

I want to see if I can use the fridge to freeze also.

This is an industrial "true" bramd SS unit.

Try the settings on the thermostat that came with the unit first. My
back bar bottle cooler would freeze just fine and yours may do the same.
The thermostat that came with the unit would go from 0F to 65F...but of
course I had to put a thermometer in the thing to set the desired temp.

Cheers,
Mike

I picked up a Beverage Air zero degree freezer and took the variable
resistor out and jumped the wires together. Then pluged the unit into my
external controler and pluged the controler into the wall. Now the freezer
goes on and off at what the controler is set for. You'll see a knob for
cooler/warmer or numbers. Take that unit out and connect the two wires
together. It will run forever like that or until you plug the unit into the
controler.
Takes about 10 minutes.

If you want to go colder, you need to find the connections to the thermostat and
connect the controller in parrallel to the contact connections there. Disconnect
the wires from the internal thermostat and connect to the controller for full
range operation. You may find that the unit will not perform well as a freezer.

Take this question to alt.home.repairs.
Great newsgroup for home projects.

Have you measured the limits on the thermostat?
My experience is that the lower limit can be as
low as 42F and the upper limit as high as 65F.

How old is it? I went through three fridges and
two freezers I got for free. Finally I bought
new "energy efficient" ones - my electric bill
dropped $120 in one year.
