Fire Hazard Appliance Recalls UPDATED NORCOLD INFO 11-20-2010

I recently had the recall part on the rear of the ref. of the Norold replaced for the 5th time. I was working when I got it home after the repair. Hopefully it will be working when I go to use it next time. I would like to know if anybody knows where i can get a magnet strong enough to reset the recall part. I would like to have one just in case this last recall part does not work. Thanks in advance for any information. William
