Admiral Gas Dryer: Igniter Glows, Flame Won't Stay Lit -... | appliancefaults.com

Technical Background:

The dryer's Main Control Unit (MCU) sends 120V AC to the igniter to initiate the heating process. As the igniter heats, it draws current. This current is sensed by the MCU. When the igniter reaches sufficient temperature, the MCU opens the gas valve solenoids. Simultaneously, the flame sensor detects the presence of the flame. The MCU relies on a continuous signal from the flame sensor to keep the gas valve open. If the flame sensor doesn't detect a flame or the igniter fails, the MCU shuts off the gas valve as a safety measure.

Symptoms:

The Admiral gas dryer's igniter glows orange, indicating it's heating up. However, after the igniter glows for a period, the gas valve clicks (or doesn't), a small flame may appear briefly, but the main burner flame does not ignite and sustain itself. Clothes remain damp after a normal drying cycle.

Possible Causes:

Faulty flame sensor (thermocouple or flame sensor rod)
Defective gas valve solenoids
Weak igniter (not drawing enough current to fully open gas valve)
Blocked or restricted vent system
Malfunctioning dryer control board (MCU)
Low gas supply pressure

Solution:

1

Unplug the dryer from the outlet.
2

Shut off the gas supply to the dryer.
3

Using a 1/4-inch nut driver, remove the dryer's front panel or access panel to expose the burner assembly.
4

Visually inspect the flame sensor for soot or damage. Clean with fine steel wool if necessary. Check for continuity with a multimeter; it should show near zero ohms when cool and change when heated.
5

Test the gas valve solenoids for continuity using a multimeter. A reading of approximately 1200-1400 ohms per coil is typical.
6

Check the igniter's resistance. Typically, it should measure between 50 and 400 ohms. If outside this range, replace it.
7

Verify proper gas pressure to the gas valve (typically 3.5-4.0 inches of water column). If low, contact a qualified gas plumber.

Safety Warning:

Disconnect power before servicing. Lock Out/Tag Out (LOTO) procedures should be followed. Gas appliances can be dangerous. If you are not comfortable working with gas, contact a qualified technician. High voltage is present when the dryer is plugged in.

Prevention:

Clean the dryer vent duct at least once a year to ensure proper airflow. Check the lint filter before each load. Periodically inspect the burner assembly for debris. A restricted vent can lead to overheating and component failure.

Expert Tip:

Many Admiral dryers have a diagnostic mode. Consult the service manual for your specific model to access error codes and run self-tests. Often, pressing and holding specific buttons simultaneously for a few seconds will initiate the diagnostic sequence.

Frequently Asked Questions

•How do I test the flame sensor on my Admiral gas dryer?

With the dryer unplugged, remove the flame sensor. Use a multimeter set to ohms to check for continuity. When cool, it should show near zero ohms. Gently heat the sensor with a lighter (away from flammable materials) and the resistance should change significantly. If it doesn't change, replace the sensor.

•What is the correct gas pressure for my Admiral dryer?

The correct gas pressure is typically 3.5 to 4.0 inches of water column (WC) at the gas valve. A manometer is used to measure this pressure. Low gas pressure can cause incomplete combustion and flame-out issues. Contact a qualified gas plumber to adjust gas pressure.

•Where can I find the service manual for my Admiral dryer model?

Service manuals can often be found online through appliance parts retailers or manufacturer websites. You will need the specific model number of your dryer to find the correct manual. Websites like AppliancePartsPros or RepairClinic often have downloadable manuals.
