Hotpoint Gas Range Igniter Clicking, Burner Won't Light:... | appliancefaults.com

Technical Background:

The gas range's Main Control Unit (MCU) sends a 120V AC signal to the igniter module. The igniter module then creates a high-voltage spark at the burner. Simultaneously, the MCU opens the gas valve, allowing gas to flow to the burner. If the igniter fails to create a spark, or the gas valve doesn't open, the burner won't light.

Symptoms:

The user reports that the igniter on their Hotpoint gas range is clicking repeatedly, but the burner is not lighting.

Possible Causes:

Faulty igniter – The igniter may be cracked, dirty, or burned out.
Clogged burner ports – Debris can block the flow of gas to the burner.
Defective gas valve – The gas valve may not be opening to allow gas flow.
Weak igniter module – The igniter module may not be providing sufficient voltage to the igniter.
Incorrect gas pressure – Low gas pressure can prevent proper ignition.
Blocked or kinked gas supply line – Obstructions restrict gas flow.

Solution:

1

Turn off the gas supply to the range at the shut-off valve behind the range.
2

Unplug the range from the outlet.
3

Remove the burner grates and burner caps. Clean the burner caps and burner heads with soap and water, ensuring all ports are clear. Use a small wire or needle to unclog any blocked ports.
4

Inspect the igniter for cracks or damage. If damaged, replace it. A continuity test with a multimeter should show a low resistance reading. If open circuit, it is defective. New igniters have a resistance around 50-200 Ohms.
5

Check the gas supply line for kinks or obstructions. Ensure the gas shut-off valve is fully open.
6

If the igniter sparks weakly, test the igniter module. Replace the module if it’s not providing sufficient voltage (typically 3-3.6V DC) to the igniter.
7

After all repairs, plug the range back in, turn on the gas supply, and test the burner ignition.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker supplying power to the range before any disassembly. Gas is flammable and can cause explosions. High voltage is present when the range is plugged in and operating.

Prevention:

Regularly clean the burner caps and burner heads to prevent clogs. Inspect the igniter for damage periodically. Check for gas leaks with a gas leak detector spray around the gas connections.

Expert Tip:

Some Hotpoint ranges have a service mode. Holding down the bake and broil buttons simultaneously for 3 seconds may enter service mode, allowing access to diagnostic codes or component testing.

Frequently Asked Questions

•How do I test the igniter module voltage?

Use a multimeter set to DC voltage. With the range plugged in and the burner selected, measure the voltage output from the igniter module to the igniter terminals. It should typically read between 3 to 3.6V DC while attempting to ignite.

•What is the correct gas pressure for a Hotpoint gas range?

Typically, natural gas ranges operate at a manifold pressure of 3.5 inches of water column (WC). Propane ranges operate at 10 inches of WC. Use a manometer to verify gas pressure at the test port on the gas valve.

•How do I check for a gas leak?

Mix a solution of soapy water (dish soap and water) and spray it onto the gas connections (fittings and joints). If bubbles form, it indicates a gas leak. Tighten the connection if possible. If the leak persists, contact a qualified technician.
