AccuTemp Steamer Ignition Module LED: 2 Flashes, Flame Sensed
Two flashes from the LED on an AccuTemp Evolution gas steamer's ignition module mean the module sees flame when nothing has asked for heat. This is a gas safety message. If gas is in the air or the burner stays lit with the steamer off, shut off power and call us.
High: the module is reporting flame without demand, which is a gas safety condition.

What does AccuTemp Ignition module LED: 2 flashes mean?
Ignition module LED: 2 flashes is the module's way of saying it senses a flame at a moment when no flame should exist. The spark ignition module watches a flame sensor and also knows whether the control has asked for heat. Normally those two facts agree: heat is called for, then flame appears. When the sensor reports flame while there is no demand, the module cannot be sure whether a flame is truly burning, a gas valve is not closing completely, or a sensor or wire is giving a false signal. It treats the situation as a safety problem and blinks twice. Depending on the cause, you may see the burner stay lit after the steamer is shut off, or the steamer may refuse to start at all. Because unburned gas or a stuck valve are real possibilities, this message is not something to test by repeated restarts. It is a signal that the flame-proving circuit and the valve need a technician's attention.
Affected models and control systems
This applies to the spark ignition module on AccuTemp Evolution gas steamers, as described in the Evolution Gas/Propane service manual. Other ignition controls use their own flash counts.
Code numbers and their meaning can change between control generations. We match the full model and control before acting on a code.
What you may notice
- The LED on the module blinks twice repeatedly
- The burner stays lit after the steamer is turned off
- The steamer refuses to start a heating cycle
Possible causes
Listed in AccuTemp's documentation
- Flame sensor or its wiring reading flame when none exists
- Gas valve not closing fully
- Heat demand signal reaching the module at the wrong time
- Ignition module failed
Other likely causes — what usually sits behind Ignition module LED: 2 flashes on this control. A technician confirms which one it is before any part is replaced.
- A flame sensor rod coated with scale so it conducts to ground and reads flame that is not there
- A gas valve seat held open by debris, letting a trace of gas keep burning
Safe checks before calling for service
- If you smell gas, go outdoors and phone the gas company.
- If the burner stays lit with the steamer off, switch off the steamer's power and call us.
- Let the cabinet cool.
- Do not open panels or touch the gas connection.
- Wait for our visit and tell us whether the burner was lit when the steamer was off.
How a technician diagnoses Ignition module LED: 2 flashes
- Confirm the two-flash pattern and note whether a burner is actually lit at idle.
- Shut off gas and power, then inspect the flame sensor and its wiring for contamination or a short.
- Test the gas valve for a complete closure and for leakage.
- Check the heat demand signal reaching the module.
- Replace the sensor, valve or module only after the test, then verify safe lighting and shutoff.
- A burner that stays lit with no heat demand is a gas safety condition that should never be tested by trial and error.
- Gas valve and flame sensor tests need gas pressure instruments and a live circuit.
- Opening panels or touching the gas connection while a flame may be present risks burns and a gas leak.
How Ignition module LED: 2 flashes differs from similar codes
One flash on this LED is a combustion air problem and three flashes is an ignition lockout. Two flashes is the reverse of those: flame sensed when none is wanted.

Is two flashes dangerous?
It is a gas safety message, so treat it seriously. If a burner is lit with the steamer off, or you smell gas, take the safety steps first.
Can I just reset the steamer?
If the burner is dark and you smell no gas, one power cycle is reasonable. If two flashes returns, stop and call us.
Is the module the problem?
Rarely the first suspect. The sensor and gas valve are tested first, and the module is replaced only if they pass.
