How to Extend the Life of Your Commercial Oven or Hob

Published: 06-07-2026

Your commercial oven and hob are the hardest-working pieces of equipment in your professional kitchen. Whilst commercial equipment is designed to be robust and be used intensively throughout the day, everything has its limit. However, most owners only think about equipment maintenance after a breakdown. In this guide, we’re covering how to take care of your commercial oven and hob to prevent breakdowns and downtime and extend your equipment’s lifespan.

 

Commercial Oven Maintenance

Why Maintenance Matters

Commercial ovens build up grease, carbon deposits, and heat stress much faster than domestic ones. Without regular servicing, you’ll see:

  • Uneven cooking temperatures
  • Longer cook times and higher energy bills
  • Food contamination risks from grease build-up
  • Breakdowns
  • Reduced lifespan

Commercial oven brands like Rational, Lincat, and Hobart design their ovens for heavy use, but even premium equipment still requires constant maintenance.

 

Daily/After-Service Cleaning

This is usually done by the kitchen staff:

  • Wipe down interior surfaces after each service
  • Remove food debris and grease trays
  • Clean door seals (important for heat retention)
  • Check glass doors for grease build-up
  • Ensure fans and vents aren’t blocked

For combi ovens, steam systems also need rinsing cycles run daily.

 

Weekly Maintenance

A deeper clean that prevents long-term damage:

  • Degrease interior walls and racks
  • Clean fan covers and air vents
  • Check door hinges and seals for wear
  • Descale steam functions if used (hard water areas are especially relevant in the UK)
  • Inspect temperature consistency with a probe

 

Monthly/Periodic Checks

This is more preventative engineering work:

  • Inspect heating elements or gas burners
  • Check thermostat accuracy
  • Test safety cut-off and door switches
  • Lubricate moving parts if required by the manufacturer
  • Check extraction/ventilation performance

 

Professional Servicing (usually 6-12 months)

A qualified engineer will typically:

  • Strip and deep clean internal components
  • Test electrical or gas safety systems
  • Calibrate temperature controls
  • Replace worn seals, fans, or sensors
  • Check compliance with safety regulations

This is especially important for gas ovens where safety certification is required.

 

Common Commercial Oven Issues Caused by Poor Maintenance

  • Hot spots or cold spots in cooking
  • Steam function failure (combi ovens)
  • Doors not sealing properly leading to heat loss
  • Excess smoke or burning smells
  • Unexpected shutdowns due to overheating

 

Commercial Hob Maintenance

Why Maintenance Matters

Commercial hobs take daily abuse: spills, boiling over pans, fat splatter, and constant high temperatures. Without routine care, you’ll typically see:

  • Uneven burner performance or hot spots
  • Ignition failures (gas hobs)
  • Slower heat-up times
  • High gas or electricity consumption
  • Increased fire risk from grease build-up
  • Reduced equipment lifespan

Well-known manufacturers like Lincat, Falcon Foodservice Equipment, and Electrolux Professional design their hobs for heavy-duty use, but even robust units depend heavily on regular cleaning and servicing.

 

Daily/After-Service Cleaning & Maintenance

This is the most important layer of care and is usually done by kitchen staff:

Gas Hobs:

  • Remove pan supports and clean thoroughly
  • Wipe burner caps and rings
  • Clear food debris from burner ports
  • Check ignition areas are free from grease
  • Clean around the control knobs

Electric/Induction Hobs:

  • Wipe ceramic or plate surfaces immediately after cooling
  • Remove spill residues before they bake on
  • Check control panels for grease or liquid ingress
  • Ensure ventilation gaps are not blocked

 

Weekly Cleaning & Maintenance

A deeper clean to prevent long-term wear:

  • Soak and degrease pan supports and removable parts
  • Inspect burner heads for partial blockages
  • Check flame quality (steady blue flame on gas hobs)
  • Check underneath hob units if accessible
  • Check for worn or loose control knobs
  • Test all zones for even heat distribution

 

Monthly/Periodic Checks

These are more performance-focused:

  • Inspect gas hoses for cracks or wear
  • Check ignition system and thermocouples
  • Verify thermostat accuracy
  • Ensure ventilation and extraction systems are working properly
  • Look for signs of overheating or electrical discolouration

 

Professional Servicing (usually 6-12 months)

A qualified engineer will usually:

  • Strip burners and deep-clean internal components
  • Tas gas pressure and safety cut-offs
  • Replace worn ignition parts or thermocouples
  • Calibrate temperature controls
  • Check electrical safety and load balance
  • Confirm compliance with gas safety regulations

 

Common Commercial Hob Issues Caused by Poor Maintenance

  • Burners not lighting or repeatedly clicking
  • Weak or uneven flames
  • Food taking longer to cook
  • Smell of gas or overheating electronics
  • Cracked ceramic glass
  • Control knobs becoming stiff or unresponsive
