Henny Penny Gas Pressure Fryer Error Code E-20C: Ignition Module
E-20C on a Henny Penny Velocity gas pressure fryer with spark ignition reports a problem with the ignition module, so the burner stays dark and the oil does not heat. If you smell gas, leave and call the gas utility. Otherwise press the Timer button once to retry ignition, and call us if the burner still does not light.
High: the burner cannot light, the fryer cannot heat, and the cause involves a gas ignition system.

What does Henny Penny error code E-20C mean?
A spark-ignition gas fryer lights its burner through an ignition module, which sends a spark and watches for a flame. If the module does not do its job, the burner does not light and the control displays E-20C. Only gas fryers with SSI ignition show this code. The module is only one link: it needs a control signal that tells it to fire, a good electrode and wire to carry the spark, and a gas valve that actually delivers fuel. When any of them fails, the burner stays dark in the same way, and the display points at the module as the place the system stopped. Staff see the code, hear no ignition and watch the oil fail to come up to temperature. One retry can succeed while a weak module still fails later, so a success after the Timer button is worth reporting. The display text is E-20C, and because gas is part of this, any smell means leaving the building first.
Affected models and control systems
Henny Penny Velocity gas pressure fryers with spark ignition (SSI), such as the PFG 600. Electric fryers do not show E-20C.
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
- E-20C on the display
- Burner dark and no flame
- Oil not reaching temperature
- No ignition clicking, or clicking without a flame
Possible causes
Listed in Henny Penny's documentation
- Failed ignition module on the gas fryer
- Worn spark electrode or damaged wire to it
- Gas valve or gas supply not delivering fuel
- Control signal that never tells the module to fire
Other likely causes — what usually sits behind error code E-20C on this control. A technician confirms which one it is before any part is replaced.
- Grease or moisture on the electrode that weakens the spark
- A module that overheated from heat soak behind the vat
Safe checks before calling for service
- Smell gas? Leave the building and call the gas utility once you are outside.
- Otherwise, press the Timer button once to retry ignition, as the owner's manual lists.
- If the burner still does not light, stop and call us.
- Do not keep repeating retries.
- Tell us whether the first retry lit and whether you heard any clicking.
How a technician diagnoses error code E-20C
- Confirm E-20C and check for gas odor.
- Verify the gas shut-off is open and supply pressure is correct.
- Watch an ignition attempt for spark at the electrode.
- Inspect the electrode gap, ceramic and spark wire.
- Test the control signal to the module and the gas valve output with a meter.
- Replace the module only after the signal, wire and valve are proven good.
- The ignition module and gas valve carry line voltage next to a fuel connection, which calls for a licensed technician.
- The module, the electrode and the gas valve each need their own test, so guessing wastes time and parts.
- Repeated ignition attempts can build up unburned gas, so retries are limited to one.

A weak module or electrode can work intermittently, so tell us it happened.
Does an electric fryer show E-20C?
No. Only gas fryers with SSI ignition show it.
