Thanks for counting on us to help with your appliance problem. My name is XXXXX XXXXX I look forward to helping you! That model does not use a typical thermostat but a thermistor. The control looks for a constant resistance signal from that thermistor and will react if you switch it out of circuit. If it has done it since new, you will probably just have to live with it, unless you want to try changing the thermistor, available below. You could, theoretically, insulate the thermistor so it reacts slower, but I cannot recommend that since it is a safety feature. The thermistor is number 15 in the diagram below.
Please let me know if you have additional questions or need clarification. There is no additional charge for any follow up help!
