Hotpoint Range Oven Igniter Slow to Light: Troubleshootin... | appliancefaults.com

Technical Background:

The oven control module (OCM) monitors the igniter circuit. When the oven is turned on, the OCM sends 120V AC to the igniter. The igniter heats up and draws current. Once sufficient current draw is detected (typically around 3.2-3.6 amps), the OCM opens the gas safety valve. If the igniter doesn't draw enough current, or the OCM is faulty, the valve won't open, or will take a long time to open.

Symptoms:

The oven igniter on your Hotpoint range takes significantly longer than usual (approximately 2 minutes) to ignite the gas and start the oven. Normal ignition should occur within 30-60 seconds.

Possible Causes:

Weak or failing oven igniter.
Partially blocked gas supply to the burner.
Faulty oven control module (OCM).
Improperly adjusted gas pressure regulator.
Loose or corroded wiring connections to the igniter or gas valve.
Defective gas safety valve.

Solution:

1

Disconnect power to the range at the breaker panel.
2

Locate the oven igniter inside the oven cavity, typically near the burner.
3

Visually inspect the igniter for cracks, breaks, or signs of burnout. Replace if damaged.
4

Using a multimeter, test the igniter's resistance. A typical igniter resistance should be between 40-400 ohms. Replace if outside this range.
5

Verify 120V AC to the igniter during startup. No voltage indicates a faulty oven control module or wiring issue.
6

Check the gas supply pressure with a manometer. It should be around 3.5-4.5 inches of water column.
7

Reassemble the range and test the oven to ensure proper ignition.

Safety Warning:

Always disconnect power to the range at the breaker panel before performing any repairs. Lock Out Tag Out (LOTO) procedures should be followed. The range contains high voltage components that can cause serious injury or death.

Prevention:

Periodically inspect the burner and igniter area for debris. Clean any spills promptly. Avoid using excessive force when cleaning around the igniter. Replace the igniter proactively every 5-7 years.

Expert Tip:

Many Hotpoint ranges have a service mode. Typically, press and hold the 'Bake' and 'Broil' buttons simultaneously for 3 seconds to access diagnostics and error codes. This can help pinpoint the issue before disassembling anything.

Frequently Asked Questions

•What is the correct resistance range for my specific Hotpoint oven igniter?

Refer to the manufacturer's specifications or the service manual for your specific Hotpoint model. If unavailable, a general range of 40-400 ohms is typical, but always verify. Some igniters draw amps instead of using a set resistance.

•How do I adjust the gas pressure regulator on my Hotpoint range?

The gas pressure regulator adjustment procedure varies by model. Typically, you'll need to remove the range's rear panel and locate the regulator. Adjust the screw or knob to achieve the correct pressure, as measured with a manometer at the burner. Consult the service manual for precise instructions and safety precautions. Incorrect adjustment can lead to dangerous gas leaks or burner malfunctions.

•Where can I find the oven control module (OCM) in my Hotpoint range?

The OCM is usually located behind the control panel or in a compartment at the rear of the range. You will likely need to remove the control panel to access it. Always disconnect power before accessing the OCM.
