Hotpoint Range Gas Smell During Broiler Use:... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) signals the gas valve to open when the broiler function is selected. The broiler regulator controls the gas pressure to the broiler burner. If the regulator malfunctions or the burner has a leak, unburnt gas can accumulate, causing the odor. The igniter must reach the correct amperage to trigger the gas valve to remain open, usually between 3.2-3.6 amps.

Symptoms:

US homeowner observes a distinct gas smell emanating from their Hotpoint range only when the broiler function is activated. The smell dissipates when the broiler is turned off.

Possible Causes:

Malfunctioning Broiler Regulator
Gas Leak at Broiler Burner Connection
Incorrect Broiler Flame Adjustment
Debris on Broiler Burner
Damaged Broiler Pan

Solution:

1

Turn off the range and shut off the gas supply valve located behind the range or in the basement/crawlspace.
2

Using a 5/16-inch nut driver, remove the broiler burner assembly.
3

Inspect the burner tube for any clogs or debris. Clean with a wire brush.
4

Check the gas connection at the burner using a soapy water solution to identify any leaks. Tighten connections or replace the gas line if necessary.
5

Visually inspect the broiler regulator for any damage or wear. If damaged, replace the regulator.
6

Reinstall the burner assembly and turn on the gas supply.
7

Light the broiler and observe the flame. Adjust the air shutter on the burner to achieve a proper blue flame with no yellow tips.

Safety Warning:

Lock Out Tag Out (LOTO) the breaker before servicing. Natural gas is flammable. Ensure adequate ventilation when working on gas appliances. If you smell gas and cannot locate the source, evacuate the premises and call the gas company immediately. Never attempt to bypass safety devices.

Prevention:

Regularly clean the broiler pan and broiler compartment to prevent food buildup. Annually inspect the gas connections for leaks using a soapy water solution. Schedule licensed technician maintenance every two years to ensure proper operation.

Expert Tip:

A common issue is a partially blocked broiler burner orifice. Use a small orifice drill bit set (available at appliance parts stores) to carefully clean the orifice. DO NOT enlarge the orifice size. Record the flame pattern before and after cleaning. This can help identify subtle improvements.

Frequently Asked Questions

•How do I properly adjust the air shutter on the broiler burner?

The air shutter controls the air-to-gas mixture. Loosen the screw on the shutter and adjust it until you achieve a blue flame with minimal or no yellow tips. A yellow flame indicates insufficient air; a roaring blue flame indicates too much air. Tighten the screw once the flame is correct.

•What type of soapy water solution is best for detecting gas leaks?

Use a mixture of dish soap and water. A ratio of 1 part dish soap to 3 parts water works well. Apply the solution to gas connections with a brush or spray bottle. Bubbles will form if there's a leak.

•How do I determine if the broiler regulator is faulty?

You'll need a manometer to accurately test the output pressure of the regulator. Consult the service manual for your specific Hotpoint range to determine the correct pressure. If the output pressure is outside the specified range, the regulator is likely faulty and needs replacement.
