Freezer doesn't run

If you got power to the unit i would put a jumper wire in the thermostat ( unplugged the unit ,open the housing where the thermostat or cold control is ,and youll see two wires connecting to it ,put a jumper wire between both with electrical tape to insulated and plugg it in , if it works replace the thermostat with the same new one ) That's the most common problem when there's power and everythig else is dead.
