reversable conversion of chest or shelf freezer to fridge for less than $15.

If you are contemplating converting your chest or shelf freezer to a fridge here is simple and cheap solution.
This is actually not a conversion at all its a simple add on so the freezer has no alterations.
Parts needed.
1plastic box about 8x4x2 in
1power cord plug too suit your country bare wire other end
1 wall mount power outlet to suit freezer power plug
1used/new thermostat and sensing tube from old ?fridge.
1 relay that has mains voltage operating coil.ie 120 or 240v ac to suit your country rated at least 10a

Construction is simply drill 3 holes in box ,one for sense tube and one for input power cord and one for thermostat control shaft
mount the thermostat and control knob
connect one input mains wire to one term of thermostat and to one of the the N/O term of relay
connect the other mains input wire to outlet socket and to one term of relay coil
connect the other thermostat term to coil term of relay.
connect the other N/O terminal of relay to outlet socket

The operation is simple the tube of thermostat is mounted with either silicon or gaf tape to inside of freezer the thermostat is set to tep you need. set the freezer control to full on.the thermostat switch operates the relay .It must have a 120 or 240v coil rating same as what your freezer is. And the contacts need to be rated at least 10 a I used a aircon relay "cheap" rated 30a" cost about $8.
The freezer just plugs into the power outlet on the box and its power cable connects to the usual freezer wall outlet.. Thats it.
use a thermometer to find a setting of about 3deg C for the "new" fridge

Photos are of the prototype done about 5 yrs ago and in constant use ever sinceand soon will be made into a nice neat box and mounting >>mmmmm
