Preventive maintenance isn't optional — it's the difference between a $200 PM visit and a $3,000 emergency repair on a Saturday night. Here's how often every piece of equipment in your commercial kitchen should be serviced.
The Complete PM Schedule
Refrigeration (Walk-ins, Reach-ins, Prep Tables) **Frequency:** Quarterly **What's checked:** - Condenser coil cleaning - Evaporator coil inspection - Door gasket condition - Temperature calibration - Drain line clearing - Refrigerant pressure check - Fan motor operation - Defrost cycle timing
Why it matters: 70% of commercial refrigeration failures are preventable with regular maintenance. A dirty condenser makes the compressor work 30% harder — cutting its life in half.
Ice Machines **Frequency:** Every 6 months (cleaning), monthly (condenser) **What's checked:** - Full system cleaning and sanitizing - Descaling (water mineral removal) - Water filter replacement - Condenser cleaning - Harvest cycle timing - Bin thermostat calibration - Water inlet valve condition
Why it matters: Health codes require ice machines to be cleaned and sanitized regularly. Scale buildup reduces ice production by up to 30% before causing a complete failure.
Cooking Equipment (Ovens, Ranges, Fryers, Grills) **Frequency:** Semi-annually **What's checked:** - Gas connection and leak check - Burner flame pattern and efficiency - Thermostat accuracy - Door hinges and gaskets (ovens) - Igniter condition - Oil filtration system (fryers) - Exhaust ventilation flow
Why it matters: Misadjusted burners waste gas and cook unevenly. A faulty igniter that clicks for 30 seconds before lighting is one click away from not lighting at all.
Combi Ovens (Rational, Alto-Shaam) **Frequency:** Quarterly **What's checked:** - Descale cycle - Steam generator inspection - Temperature probe calibration - Door seal condition - Drain valve function - Software updates (where applicable) - Fan motor bearings
Why it matters: Combi ovens cost $15,000-40,000. A $250 quarterly PM extends the life by 3-5 years. The descale cycle alone prevents the most common failure mode.
Dishwashers **Frequency:** Quarterly **What's checked:** - Wash and rinse temperature verification - Chemical dispenser calibration - Spray arm condition - Door gasket and curtain - Pump and motor inspection - Drain system - Deliming
Why it matters: A dishwasher running at wrong temperatures fails health inspection. Low rinse temperature means sanitization isn't happening.
Kitchen Ventilation (Hoods, Exhaust Fans, Makeup Air) **Frequency:** Quarterly (fan service), semi-annually (air balancing) **What's checked:** - Fan belt tension and condition - Motor bearings and lubrication - Exhaust airflow measurement - Makeup air balance - Filter condition - Fire suppression system inspection - Grease buildup assessment
Why it matters: Improperly balanced kitchen ventilation wastes energy, creates uncomfortable conditions for staff, pulls conditioned air from the dining room, and is a fire code compliance issue.
The Cost Comparison
| Scenario | Cost |
|---|---|
| Quarterly PM program (all equipment) | $1,200-2,400/year |
| Average emergency repair call | $450-800 per incident |
| Walk-in compressor failure (emergency) | $2,500-5,000 |
| Failed health inspection | $500+ fine + closure |
| Lost revenue during equipment downtime | $500-2,000 per hour |
A $200/quarter PM visit that prevents one $2,500 emergency repair pays for itself 3x over.
How PM Contracts Work
Most equipment service companies offer PM agreements with:
- Scheduled visits at set intervals
- Priority response for emergencies
- Discounted labor and parts rates
- Written documentation for health inspections
- Equipment inventory tracking
The best time to set up a PM program is before something breaks.
