Heating a Microwave Corn Heating Pad is Easy!

If you follow these instructions on this page, you should enjoy your Cornbag Warmer for many years!! We hope you fall in love with yours just like we have!

Microwave Corn Heating Pad - Heating Instructions

Follow these steps to heat your Cornbag Warmer:

  1. ONLY use a Microwave Oven.
  2. Your microwave MUST have a turntable to prevent overheating and/or hot spots.
  3. Leave the outer decorative cover on (see below if it's not clean!).
  4. Place your warmer toward the center of the microwave oven bottom. You may have to fold it over on itself if it doesn't fit.
  5. The warmer should be the only thing in the microwave.
  6. If the warmer is cold, set the time based upon the table below. You will need to adjust your heating time based upon how hot your warmer gets using the times in the table. This is a trial and error process until you get a feel for how your microwave heats
  7. If the warmer has already been heated (i.e. it isn't cold), then heating times will be less.
  8. If your microwave has a shelf of any kind, don't use it unless it is made of glass or heat safe plastic.
  9. If your microwave is the kind that only requires you to press one button to turn it on, you must double check how long you turned it on for to insure you didn't press the wrong button.
  10. We encourage you to watch your warmer as you heat it the first few times until you get a feel for how your microwave heats.
  11. Stay nearby when heating your warmer... don't leave!

Helpful Tips

  • If you've overheated your warmer - be careful! It will be hot so let it cool in a safe area before using it.
  • The heating recommendations are based upon years of experience using 1000 watt microwaves (the most common kind). If using a microwave greater than 1000 watts, the heating times will be less.
  • Never use a Corn Bag Warmer with an infant or toddler or anyone who cannot communicate properly.
  • An adult should always test heated warmers before letting the kiddos use them.
  • Corn Bag Warmers give off Moist Heat - make sure that wherever you set a heated warmer can tolerate the heat and moisture that will be given off.
  • If your microwave oven does not have a rotating platform (carousel), do not use it.
  • Never use a conventional oven or anything other than a microwave oven.
  • Don't use an industrial microwave like they have in food service.
  • If the outer cover has oil or anything flammable spilled on it, it MUST be cleaned before use.
  • Finally, if the inner corn bag has anything spilled on it, your warmer smells burnt or appears to be damaged in any way, Don't use it - contact us for a replacement.
