One of the most vulnerable components on your tumble dryer is the heating element - especially if you’re in the habit of opening the door while the dryer is still running. Your tumble dryer uses a heating element to heat the air being drawn into the drum. If you notice that your tumble dryer isn't heating properly, then use this genuine Hotpoint A2 Heater to ensure that an essential part of your dryer's heating system is working correctly. Please check the model fit list to ensure that this part is correct for your model.
