Our Duraflace 1500 electric infrared heater has one element that seems to be damaged and burnt out. Is this replaceable? How do I replace it? I already took it apart to find the damaged element.

If your dryer heating element does not cycle, you may have a bad high limit thermostat. The thermostat is used to regulate the internal temperature of the dryer and should cycle the heater on and off. The thermal cut-out is supposed to prevent the dryer from overheating and will blow like a fuse. It is a non-resettable device and must be replaced. It is strongly recommended that you replace both these components at the same time if you have found one of them to be bad. Both of these components will be mounted on the heater box housing. Usually the thermostat is the component closest to the ceramic terminals of the heating element. Most manufacturers sell these two components as a set. The dryer temperature at the exhaust on the back of the dryer should be about 140 degrees. If the temperature is excessive to the point where it is melting things and the cabinet is too hot to touch, make sure the heater is regulating as it should. I would use some extreme caution about using your dryer until you have this problem corrected. I would not use it under any circumstances if you are not going to be home, or if you are going to bed. Dryers are one of the number causes of fires in homes. Good luck to you and let me know if I can help any further.

SOURCE: Kenmore electric stove heating element how to replace

A replacement is usually around $40. There are usually 2 screws holding the element in the back of the stove. Turn off the power and remove the element. There are usually only 2 wires. It really doesn't matter which goes where. Install the new element and see if it will shut off when oven reachers temp. If it continues to heat, there is another piece that needs to be replaced. If there is a contactor or relay replace it, If not the thermostat needs to be replaced. Sometimes when the element burns out it shorts to the ground and fuses the contacts forcing the element to stay on. Sometimes you actually have to turn off the power to the stove.

Did you replace burnt fuse/tripped breaker?

SOURCE: I have an AO5 error

This indicates a power fault inside the actual heater. Have you tried unplugging the heater, letting it sit for a good 2 minutes, and replugging it back in? If the problem persists you will unfortunately need a repair. Please let me know if you need more information on this. You can also contact comfort zone, the manufacturer, located in Canada, at 780-420-6572.

Thanks so much for the question,
