In a restaurant, a broken appliance isn't an inconvenience. It's product in the trash, a menu with items crossed off, and potentially a problem with the health department. This guide is for owners and kitchen managers running cafés, restaurants, bars and small food shops in Montgomery and Prince George's counties. It covers the equipment that most often causes trouble, the routines that prevent it, and how to handle a failure without losing more than you have to.
What the inspector is looking at
Both counties license and inspect food service facilities. In Montgomery County that's the Department of Health and Human Services' Licensure and Regulatory Services; in Prince George's County it's the Health Department's environmental health division. Both describe two main kinds of routine inspection: a comprehensive inspection, covering sanitation, maintenance and food handling across the whole facility, and a monitoring inspection that focuses on critical food temperatures, equipment temperatures and handling practices.
Under Maryland's food service regulations, potentially hazardous cold food has to be held at 41°F or below. So a reach-in or prep rail that drifts to the mid-40s on a busy afternoon isn't just a mechanical problem. It's a violation waiting to be written up, and product you may have to discard.
That's why the most useful piece of equipment in the kitchen may be a cheap thermometer in every cold unit, and someone who checks and logs them.
The equipment, ranked by how much it hurts to lose
Refrigerated prep tables
Sandwich and pizza prep tables are under the most stress in the kitchen. The lids are open for hours, the pans sit in warm air, and the table often lives next to a fryer or flat-top. They are also the unit most likely to fail the temperature check first.
Watch for:
- •Pans on the rail running warmer than the cabinet below.
- •A lid left up through slow periods. Close it whenever you can.
- •Pans overfilled above the rail, where cold air doesn't reach.
- •Ice building on the evaporator coil inside the cabinet.
Reach-in coolers and freezers
Reach-ins are durable, but they depend completely on the condenser being able to shed heat. In a kitchen, that condenser pulls in air loaded with grease and flour. A coated condenser makes the compressor run longer and hotter until something gives.
Signs a reach-in is struggling: it runs constantly, the cabinet recovers slowly after the door is opened, the compressor area is very hot, or a thin layer of frost becomes a thick one.
Walk-ins
A walk-in's problems are usually slower. Door gaskets tear, the door closer stops pulling the door shut, the strip curtain goes missing, and the evaporator ices up. If you find the door propped for deliveries, or ice forming around the frame, fix those before they cost you the compressor.
Ice machines
Food safety rules treat ice as food, so ice machines need regular cleaning and sanitizing to stay that way. Slime and scale build inside the water system even when the bin looks clean. Follow the maker's cleaning procedure and interval, and keep the water filter current. Minerals in the incoming water slowly coat the evaporator plate, and a machine that's overdue for descaling makes thin, slow or cloudy ice before it stops. Our ice maker guide covers the residential side; commercial brands like Hoshizaki, Manitowoc and Scotsman follow the same logic with bigger consequences.
Cooking equipment
Ranges, convection ovens and fryers fail more visibly: a pilot that won't stay lit, an oven that won't reach temperature, a fryer that won't hold its setpoint. For gas equipment, the rule is the same as at home. If you smell gas in the kitchen, get everyone out, don't operate switches, and call 911 and the gas company's emergency line from outside.
Dish machines
A dish machine that doesn't reach its rinse temperature, or isn't dosing sanitizer correctly, can create an inspection problem even though the dishes look clean. Check the gauges or test strips as the operator's manual directs.
A maintenance routine that actually happens
The best maintenance plan is the one staff will follow on a Tuesday night. Keep it short and put it on the wall.
Every shift - Read and log the temperature of every cold unit. - Close prep table lids when not in active use. - Keep doors clear of boxes so they close fully.
Weekly - Wipe door gaskets with warm water and look for tears. - Check under units for water or ice. - Clear anything stacked against condenser grilles.
Monthly - Brush or vacuum condenser coils on reach-ins and prep tables (units unplugged). Kitchens with heavy frying may need this more often. - Check ice machine air filters where fitted.
On the maker's schedule - Clean and sanitize ice machines. - Replace water filters. - Descale dish machines and combination ovens.
When a unit fails during service
- Move the product first. Consolidate into working units, or pack into coolers with ice. Write down the time and temperature when you found the problem.
- Check the obvious. Is it plugged in? Did a breaker trip? Is the condenser choked? Is the door or lid sealing?
- Don't keep resetting it. A compressor that trips repeatedly can be damaged by constant restart attempts.
- Call with details. Read us the brand and the model and serial numbers printed on the unit's nameplate, the temperature it's reading, and your hours.

Making a repair visit go smoothly
- •Tell us when your quiet window is. A technician can't pull a prep table apart while it's feeding the line.
- •Make sure someone on site can approve the quote, or tell us who can.
- •Clear the space in front of and behind the unit if you can.
- •Mention every piece of equipment that's acting up.
Diagnosis happens in your kitchen. You'll get the failed part, the reason it failed, and a quote addressed to whoever signs off. Parts are matched to the model; we'll tell you when one is an equivalent. If a unit is old enough that repair is poor value, we'll say so. Our repair or replace guide covers the reasoning.
