Hotpoint Oven Heating Element Cracks or Blisters:... | appliancefaults.com

Technical Background:

The oven's electronic control (MCU) sends 240V AC to the heating element via a relay. The element's resistance generates heat. Cracks or blisters indicate a breakdown in the element's internal structure, leading to inconsistent resistance and potential shorts.

Symptoms:

US homeowners report their Hotpoint oven is not heating properly or at all. They may observe visible cracks, blisters, or hot spots on the heating element itself. Some might also notice a burning smell during operation or see sparking.

Possible Causes:

Heating element failure
Overuse at high temperatures
Manufacturing defect
Age and normal wear and tear
Voltage fluctuations

Solution:

1

Disconnect power to the oven at the breaker panel (LOTO - Lock Out Tag Out). Verify no voltage present at the oven receptacle with a multimeter.
2

Locate the heating element, usually at the bottom of the oven cavity. Sometimes it's held by clips instead of screws.
3

Remove the screws securing the heating element with a 1/4-inch nut driver. For clips, carefully pry them open.
4

Carefully pull the heating element out far enough to access the wire connectors. Note the wire connections before disconnecting.
5

Disconnect the wires from the heating element. Use needle-nose pliers if needed to gently remove the connectors.
6

Using a multimeter, test the heating element for continuity. Set the multimeter to Ohms. A reading of OL (open line) or very high resistance indicates a failed element. A good element should read between 19-24 Ohms.
7

Replace the heating element with a new one. Ensure the replacement is compatible with the Hotpoint oven model. Reconnect the wires securely and reassemble.

Safety Warning:

Electrical shock hazard! Always disconnect power at the breaker panel before working on the oven. Verify the circuit is de-energized with a multimeter before touching any wires or components. The oven operates on 240V AC, which can be lethal.

Prevention:

Avoid using the self-clean function excessively, as it subjects the element to extremely high temperatures. Periodically inspect the element for any signs of damage.

Expert Tip:

Some Hotpoint ovens have a hidden service mode that displays diagnostic codes. To enter, press and hold the 'Bake' and 'Broil' buttons simultaneously for 5 seconds. Use the up/down arrows to navigate the menu. Check for any error codes related to the heating element circuit.

Frequently Asked Questions

•How do I find the correct replacement heating element for my Hotpoint oven?

Locate the model number of your oven. It's typically found on a sticker inside the oven door or on the back panel. Use this model number to search for compatible replacement heating elements online or at appliance parts retailers. Verify voltage and wattage are correct.

•What if the new heating element also cracks or blisters after a short time?

This could indicate a problem with the oven's control board or a voltage issue in your home's electrical system. Have a qualified electrician check the voltage at the oven receptacle to ensure it's within the acceptable range (220-240V AC). If the voltage is too high or fluctuating, it can damage the heating element.

•Can I repair a cracked heating element instead of replacing it?

No, it is not recommended to attempt to repair a cracked heating element. The cracks indicate a breakdown in the element's internal structure, and any repair would be unreliable and potentially dangerous. It's always best to replace the element with a new one.
