If your freezer is not running, it might be due to one of the following reasons:
The control knob is turned to OFF. Simply set the knob back to ON.
A fuse is blown in your house, or a circuit breaker is tripped. If this is the case, reset the circuit breaker or replace the fuse with a 15 amp time-delay fuse.
The power cord may not be plugged in. Check to be sure the plug fits tightly into the wall outlet. Note: Do not use an extension cord.
A power outage has occurred. In this case, you might want to call your local electric company.
