What RESET IGNITION
actually means.

Each time a Middleby Marshall gas conveyor starts, it purges the chamber with the blower, sparks the burner and proves the flame. If that sequence ends without a steady flame, the X-Series shows RESET IGNITION. The manual gives three causes: gas not turned on to the oven, gas pressure too low and a burner that has stopped running.

What to do when RESET IGNITION shows on the pizza oven

Before you book,
in this order.

Each step comes from Middleby Marshall's own guidance for RESET IGNITION on its pizza ovens. Follow it to the end: the last card says whether this is a visit.

01

Press Dismiss and follow the prompts on the screen.

02

Make sure the manual gas valve on the supply to the oven is open, as it may have been shut for cleaning or after a delivery.

03

Turn the oven off and back on to clear the message and let it run its own relight sequence; do not try to light the burner any other way.

04

If RESET IGNITION returns, or you smell gas at any point, turn the oven off, close the gas supply and book a visit; a gas smell means leaving the area and calling the gas utility from outside.

What not to do

RESET IGNITION is not a temperature sensor report; the probes have their own messages, PROBE # OPEN and ALL PROBES OPEN. An oven that lights but never reaches its set point shows HEATING ERROR instead.

Questions
about RESET IGNITION.

Can I clear RESET IGNITION myself?
Press Dismiss and follow the prompts on the screen. If it comes back, it needs a visit.
How many times does a Middleby Marshall conveyor try to relight?
The PS638 manual describes three spark and purge cycles before the ignition locks out. After that, turning the oven off and on starts the full sequence again.
Why does my Middleby Marshall X55 show RESET IGNITION every morning?
A gas valve left closed overnight is the simplest reason. If the valve is open and it still happens, low gas pressure or a worn igniter or flame sensor is likely, and that needs a technician.
Is RESET IGNITION dangerous on a Middleby Marshall?
The oven shuts the gas when it cannot prove a flame, which is what it is designed to do. Any smell of gas changes that: close the supply, leave the area and call the gas utility from outside.

Back to your everyday

Still showing RESET IGNITION?

A booking with a code goes further when it has the code copied as shown, the model and serial from the rating plate, and a note on whether the oven still lights, heats or moves its belt. With those three, the office can match the likely part to your oven the same day.
