Hotpoint Range Broiler Igniter Glowing But Not Heating:... | appliancefaults.com

Technical Background:

The Hotpoint range uses an igniter to ignite the broiler burner. The oven control board (MCU) sends 120V AC to the igniter. As the igniter heats up, its resistance decreases, allowing more current to flow. When the current reaches a certain threshold (typically around 3.2-3.6 amps), the MCU opens the gas valve to the broiler burner. If the igniter is weak, it may glow but not draw enough current to open the gas valve fully or reliably.

Symptoms:

The homeowner observes that the broiler igniter glows orange but the broiler burner does not ignite fully, or takes a very long time to ignite. The food is not broiling properly.

Possible Causes:

Weak or failing broiler igniter
Insufficient gas pressure to the range
Faulty oven control board (MCU)
Blocked or partially obstructed burner ports
Incorrect voltage supply to the igniter
Damaged or loose wiring to the igniter

Solution:

1

Disconnect power to the range at the breaker panel (LOTO).
2

Locate the broiler igniter assembly inside the oven cavity.
3

Using a multimeter, test the igniter for continuity. A reading of OL or very high resistance indicates a failed igniter.
4

Verify the voltage to the igniter during broiler operation. You should measure approximately 120V AC at the igniter terminals.
5

Check the gas supply pressure to the range using a manometer. Typical pressure is 4-6 inches of water column.
6

Inspect the burner ports for any obstructions. Clean with a wire brush if necessary.
7

If the voltage and gas pressure are correct and the igniter is new, suspect a faulty oven control board (MCU).

Safety Warning:

Always disconnect power to the appliance before performing any repairs. Lock Out / Tag Out (LOTO) the breaker. The range operates on 120V AC and 240V AC – high voltage is present. Ensure the gas supply is shut off when working on gas components.

Prevention:

Periodically inspect the broiler burner ports for debris. Avoid using aluminum foil directly on the oven floor, as it can reflect heat and damage the igniter. Clean up spills promptly to prevent them from baking onto the burner assembly.

Expert Tip:

Some Hotpoint ranges have a service mode that allows you to manually activate the broiler igniter and gas valve for testing purposes. Refer to the service manual for instructions on entering service mode. Often, pressing and holding the 'Bake' and 'Broil' buttons simultaneously for 5 seconds will initiate the diagnostic mode.

Frequently Asked Questions

•How do I access the broiler igniter in my Hotpoint range?

The broiler igniter is typically located at the top of the oven cavity, behind a metal shield or cover. You may need to remove the broiler pan and rack to access it. Some models require removing screws to detach the shield.

•What type of igniter does my Hotpoint range use (flat or round)?

Refer to the parts diagram for your specific model number. You can find this information on the Hotpoint website or appliance parts retailers. Provide your model number for accurate identification.

•How can I tell if my oven control board (MCU) is faulty?

A faulty MCU can cause various issues, including failure to send voltage to the igniter, erratic temperature control, or error codes on the display. Testing the MCU requires specialized tools and knowledge. If you suspect a faulty MCU, it's best to consult a qualified appliance repair technician.
