What should I do if my refrigerator won't operate?

First, check if the power cord is unplugged and plug it into a grounded 3 prong outlet. Test if the outlet is working by plugging in a lamp. Check if a household fuse is blown or circuit breaker is tripped - replace the fuse or reset the circuit breaker. Make sure the refrigerator controls are on. If it's a new installation, allow 24 hours for the refrigerator to cool completely.
