Who writes
the guides.

Every page on this site grows out of service calls to working businesses, booked after close, before the doors open or in the quiet hour between lunch and dinner. We add a subject once managers keep describing it in the same words: a walk-in that climbs past a safe holding temperature overnight, a fryer slow to recover between baskets, a combi oven that stops making steam, a dish machine short of its rinse heat, or a row of laundry machines that will not spin.

What we write comes from equipment our technicians have opened on site, panels off, coils lit with a flashlight and readings taken with their own meters and probes. A displayed code gets explained here only when its maker has put that meaning on paper. Sentences resting on a manual link to it, and sentences resting on our own service calls say so plainly.

How a guide
is written.

Four rules every guide on this site follows, from the first question to the last revision.

01

Subjects come from the managers who call

Topics follow the words owners, chefs and shift leads use when they book a visit, and each guide opens with what staff can safely do first: move product to a working unit, write down the temperatures, write down whatever the screen shows, and take the machine out of use.

02

Checked against makers' published documents

Cleaning and deliming steps, chemicals a maker allows, holding and rinse temperatures, and the meaning of any displayed code come from the equipment makers' own manuals and bulletins, and any line leaning on such a document cites it by name.

03

Gas, grease fire, food safety and water limits

These limits apply on every page here. Gas odor on the line: close the gas at the appliance or at the main, no lighters, no switches, air the space out, clear the building and ring the gas utility or 911 from the parking lot or street. Fire in a fryer or grease: the hood suppression system and a Class K extinguisher as the staff were trained, never water, and 911. Cold storage warm with food above 41°F: move product to working units, log the temperatures and follow the FDA Food Code on discard. Water pooling near power: keep everyone back and kill the circuit at a panel standing on dry floor. A hot electrical odor: switch that circuit off. Staff are never asked here to loosen a gas fitting or a refrigerant line, open a live electrical panel, or reach into a fryer vat or a machine drum.

04

First published and last revised dates

Each guide shows the day it went live and, next to it, the day it was last reworked; that second day moves forward whenever a maker's document behind the guide changes.

Questions about
the guides.

Who writes these commercial appliance repair guides?
The technicians who handle our commercial service calls; their findings at coils, burners, vats, boosters and drums are then compared with what the equipment maker publishes.
Is any restaurant equipment maker behind these guides?
None. Our commercial service is independent of every maker; no maker pays for a page here or sees a draft before publication.
Where do I send a correction to a commercial kitchen guide?
Write to us through the site's form, quoting the link and the line you believe is off. Once we confirm the problem, we rewrite the passage and the page shows a newer rework date.
