Hotpoint brand ovens, manufactured by the General Electric (GE) Corporation, are available in gas and electric models in a variety of sizes and finishes. If a Hotpoint oven does not heat as expected, performing some troubleshooting can help identify the issue and find a resolution, before you resort to calling a repairman.
Verify that the Hotpoint oven is connected to a grounded power supply. Check your home's circuit breaker or fuse box to see if the breaker for the oven has flipped or its fuse has blown. If it has, reset or replace the circuit breaker or fuse.
Confirm that a cooking temperature has been selected and that the "Start" button has been selected or pressed to begin heating or cooking the food.
Unlock the door if the "Self Clean" cycle has recently completed. The oven must cool properly prior to being able to unlock the door or start a new cooking cycle.
Verify that the surface units are lit on a gas model prior to relighting an oven pilot light that has gone out, which can cause the oven not to heat. Remove the oven door and the racks inside the oven. Take out the screws on the back of the oven bottom and place your fingers inside the slots on each side of the oven bottom. Lift the back of the oven bottom first and then pull it out. The pilot light is located in the bottom rear of the oven on the left side of the burner. Push in the control knob and hold it down while using a lighter or match to light the pilot light. Hold down the control knob for 30 seconds after the light is lit and then release. Replace the oven bottom, racks and door.
Contact an authorised service technician if the above procedures do not resolve the problem.
If the oven is gas powered, stop immediately if a gas odour is detected. Leave the house and contact your gas company or fire station for help.
