Product review (1 stars): Short life
The one I purchased worked for less than 6 weeks and then melted thru in the center,  melted the aluminum support frame and was essentially a fire hazard.  I am relieved that it did not damage the inside of the freezer or burn our house down.  I am hoping that it did not destroy any other components when it burnt up.  The voltage is proper and the defrost timer and thermostat are both new GE parts.  The Customer service was very quick to respond and offered a solution and a return label so I could return the defective unit. I will update as soon as this is resolved with the outcome.  I have now purchased a genuine GE part to replace this Generic unit and I hope it last another 13 years like the original heater did.  It looks as if the other reviews are good and that is why I purchased this one,  hope it was just a defective unit and others do not have the same issue I had.
