Our recently acquired Crosely refrig/freezer has a feature that we would like to disable. There seems to be a heating element in the refrigerator frame that the doors set in. It may be there to prevent condensation on the refrigerator gaskets but it operates well above room temperature and is "on" all the time. We would like to disable this feature as it will surely make the unit more expensive to operate and we want to keep our utility bills to a minimum. Thanks for any help you can provide.
