Platinium Refrigerator thermostat

[andi.luc1989]

Hello,

I have a small fridge, it's almost the dimensions of a cooker. Its thermostat was faulty, the refrigerator was running continously. I decided to buy another one. Because i couldn't find its original type, i bought a K59 Ranco.

It has a compartment that it's not quite a freezer, but keeps things cool at maximum -6 Celsius (I use the external sensor of a weather station to measure).

I noticed that the K59 thermostat has a big difference between on and off temperatures. If i set it close to maximum, it stops the compressor at -6 Celsius and turns the compressor on at +2 Celsius. So the things in the `freezer` go through a frost/defrost cyle :(

I would like to find a thermostat that turns the compressor OFF at -6 and turns it on at -4 Celsius. I would like something with a switching value of 2-3 Celsius.

Here i have available the range from the company above. They have datasheets there (brochures, instructions download). Can you help me with choosing one thermostat?

Thank you

you need to put an ranco thermostat suitable for a freezer , as there is an ice box on top(compartment)

Thank you. I looked for that,but they are described as `refrigerator thermostat`, not freezer thermostat.
K59 has operating range of -32 +6 Celsius
K60 operating range -40 + 40 Celsius

What is the difference as i don't need to adjust a temperature over +6 Celsius? (K60 goes to +40 Celsius)

You can use -40 to +40 its a common thermostat
