Cross-checkedBrands: Maytag4 components

Whirlpool-built Maytag gas range with five sealed burners, convection and air fry with a basket, 5.0 cu ft oven. 120 V for igniters, control and convection fan. Gas-side work goes to a licensed gas tech.

Safety first

If you smell gas: no switches or flames, get everyone out and call the gas utility from outside.
No work on the gas valve, regulator, orifices, burner adjustment, LP conversion or gas line: that is licensed gas-tech work. This sheet covers the electrical side only.
Unplug the range before opening panels; the igniter circuit and controls are 120 V.
Anti-tip bracket must be installed and engaged.

How it works

Spark ignition on the cooktop; hot-surface igniter on the oven burners.

Simmer burner runs from about 800 to 5,000 BTU.

Convection fan and air fry basket; the control reports faults as Whirlpool F#E# codes.

Ranges and wall ovens: reading F-codes and F#E# codes (GE, Whirlpool family) and when a reset is safe

Oven F-codes point to a circuit: temperature sensor, door lock, keypad or control. GE ovens show F plus a number; Whirlpool-family ovens show F#E#. Both makers tell owners to clear the display, cut power at the breaker for a short time and watch whether the code returns. A code that returns is a real fault. An over-temperature code is a safety stop: do not keep using the oven.

Oven door glass cracked or shattered: make it safe, document it, and quote the door glass

Oven doors use tempered glass, which breaks into small pebbles instead of shards. Earlier damage (a chip from a rack, a knock with a pan, a scratch) can weaken it so it fails later, even when the oven is cold. A cracked panel must not be heated again: the oven stays out of service until the glass or door is replaced. The job is to make the area safe, record model, serial and photos for a warranty or safety claim, and order the correct glass pack.

Grease or stains between the oven door glass panes: how to open the door and clean it

Grease and splatter work their way between the panes through the door's vent slots and edges. The only thorough fix is to take the door off and separate the panes; a cloth on a thin stick pushed through the bottom slots gives a partial result without disassembly. The risks are breaking or chipping tempered glass and losing track of screws and spacers.
