What E2 means on a Whirlpool dryer
The E2 error code on a Whirlpool gas dryer indicates a Top Burner Ignitor fault condition. Specifically, the control board monitors the voltage on the burner return signal line. Under normal ignition, the system expects the burner return signal to begin at 120V and then transition down to 0V within a predefined time window, confirming that the ignitor has heated sufficiently and the gas valve has opened to sustain a flame. When that transition from 120V to 0V does not occur within the allowed timeframe, the control increments a fault count and logs the E2 code.
This fault points directly to a problem in the ignition circuit of the top burner assembly. The components most involved include the ignitor itself, the radiant flame sensor (also called the radiant sensor or ignitor sensor), the gas valve coils (specifically the holding and booster coils), and the wiring harness connecting these components to the control board. If any of these components fail to complete the circuit transition correctly, the control board will never see the 0V return signal it requires, triggering the fault.
Common root causes include a burned-out or weakened ignitor that draws insufficient current to activate the radiant sensor, a failed radiant sensor that does not close the circuit to the gas valve coils even when the ignitor is glowing, or a gas valve coil set that has failed open. Wiring issues such as loose terminals, corroded connectors, or broken wires in the burner circuit can also prevent the signal transition. In some cases, inadequate gas supply pressure can prevent ignition even when the ignitor and sensor are functioning correctly.

Common causes of E2
- 01
Failed or Weakened Ignitor
Part replacementThe ignitor is the most common failure point in this circuit. Over time, ignitors become brittle and either crack completely or degrade to the point where they no longer draw enough current to activate the radiant sensor. Visually inspect for cracks, and measure resistance to check for an open circuit.
- 02
Defective Radiant Flame Sensor
Part replacementThe radiant sensor sits next to the ignitor and is designed to close the gas valve circuit once the ignitor reaches the correct temperature. A failed sensor will not close even with a functioning ignitor, preventing the voltage transition the control board is waiting for. Testing requires checking continuity at operating temperature.
- 03
Failed Gas Valve Coils
Part replacementThe gas valve relies on a set of coils (booster and holding coils) to open and allow gas flow. If one or more coils fail open, the valve will not open, the burner will not ignite, and the return signal will never drop to 0V. Each coil can be tested individually with a multimeter for continuity.
- 04
Wiring or Connector Fault in the Burner Circuit
Wiring / connectionLoose, corroded, or broken wire connections between the control board and the burner assembly components can interrupt the return signal path. Inspect all terminals at the ignitor, sensor, and gas valve coil connectors for corrosion, heat damage, or backing out of the connector housing.
- 05
Insufficient Gas Supply Pressure
Wiring / connectionIf the gas supply pressure to the dryer is too low, the burner may fail to sustain ignition even when the ignitor and sensor are working correctly. Check that the gas shutoff valve is fully open and verify that other gas appliances in the home are operating normally.
