Microwave - Use of Extension Cords

We strongly recommend that an extension cord not be used with a Microwave due to potential safety hazards under certain conditions. Your Microwave should be plugged into its own properly grounded, dedicated electrical outlet to prevent the flickering of the lights, blowing of a fuse or tripping of a circuit breaker. The power cord on a Microwave is typically three to five feet long, depending on the model.
 

Using an Extension Cord with a Microwave

Extension cords may be used if the following conditions are met:
 
  1. The extension cord must be a three-wire grounding type appliance cord that has an Underwriters Laboratory (UL) approval and mentions the current it can handle. The extension cords are usually marked 15 or 20 amps.
  2. The marked electrical rating of the extension cord should be at least as great as the electrical rating of the Microwave.
  3. The extension cord should be placed so that it cannot be pulled on or tripped over.
Where a standard 2-prong wall outlet is encountered, it is your personal responsibility and obligation to have it replaced with a properly grounded 3-prong wall outlet.
 
These types of extension cords are obtainable through home improvement stores, hardware stores, etcetera. If you do use an extension cord with your Microwave, the interior light may flicker and the fan or blower sound may vary when the Microwave Oven is in use. Cooking times may also be longer.
