Roper Range Gas Smell Only When Using Broiler:... | appliancefaults.com

Technical Background:

The Roper range utilizes a gas valve controlled by the electronic control board (MCU). When the broiler is selected, the MCU energizes the broiler gas valve, allowing gas to flow to the broiler burner. Proper burner alignment and sufficient air mixture are crucial for complete combustion. Incomplete combustion results in unburned gas and the associated odor.

Symptoms:

The homeowner reports a distinct gas odor emanating from the Roper range only when the broiler function is activated. The smell is not present during regular oven operation.

Possible Causes:

Partially open broiler valve
Improper broiler burner alignment
Gas leak in broiler supply line
Insufficient ventilation around broiler burner
Debris or food buildup on the broiler burner
Malfunctioning gas pressure regulator

Solution:

1

Turn off the range at the breaker panel.
2

Locate the gas supply line to the range and shut off the gas valve.
3

Inspect the broiler burner and surrounding area for any visible debris or food buildup. Clean with a brush and vacuum.
4

Check the broiler burner alignment. Ensure it's correctly positioned within the broiler compartment. Use a 5/16-inch nut driver to adjust if necessary.
5

Apply a gas leak detection solution (soap and water) to all gas connections in the broiler supply line, including the valve and regulator. Look for bubbles, indicating a leak.
6

If a leak is detected, tighten the connection with an appropriate wrench. If tightening doesn't stop the leak, replace the faulty component.
7

Once repairs are complete and no leaks are detected, turn on the gas supply and the breaker. Test the broiler operation and monitor for any gas smell. Check gas pressure with a manometer, should be around 10 inches WC.

Safety Warning:

Lock Out/Tag Out (LOTO) the breaker panel before performing any repairs. Gas appliances can be dangerous if not handled properly. If you are not comfortable working with gas, contact a qualified technician. Natural gas is flammable and can cause explosions. High voltage is present even with the appliance turned off.

Prevention:

Regularly clean the broiler compartment to prevent food buildup. Ensure adequate ventilation around the range. Periodically inspect gas connections for leaks using a gas leak detector.

Expert Tip:

The Roper range often has a hidden service mode. Simultaneously press and hold the 'Bake' and 'Broil' buttons for 5 seconds to access diagnostic codes and sensor readings.

Frequently Asked Questions

•What is the proper gas pressure for the Roper range broiler?

The gas pressure for the Roper range broiler should be approximately 10 inches of water column (WC) when measured with a manometer at the test port.

•How do I adjust the broiler burner flame?

The broiler burner flame is typically adjusted by rotating the air shutter located at the burner's inlet. Adjust the shutter until you achieve a blue, stable flame without yellow tips. More air creates a bluer flame.

•What type of gas leak detector solution is recommended?

A commercially available gas leak detection solution or a mixture of mild dish soap and water can be used. Avoid solutions containing ammonia, as they can corrode gas fittings.
