Review: Reasonably priced solution if your compressor does not want to start up. Worth a try before calling a technician. Worked for me and saved having to buy a new fridge for the garage. Make sure you you match up the amp draw of your compressor to the unit as there are 3 variations available. There are several videos on Utube to walk you through installation. Fast shipping.

Fixed my Kenmore Deep Freezer. Know this- you need to wire the freezer thermostat in series so the freezer shuts the 3 in 1 off or it’ll run forever. I did this by looking at the wiring diagram. It showed the brown wire was thermostat. I connected on of the black power circuits to that and it works good as new and turns on when thermostat calls for cooling and off when cooled sufficiently. So far so good! Cheap fix. But need to know a little about electrical work.
