Well, Rail, or Base — Which Side Is Failing?
Prep tables have two distinct cooling zones that can fail independently: the refrigerated well or rail on top (holding pans of prepared product) and the refrigerated base cabinet underneath (storing backup product). Intake asks which zone is warm so the dispatched provider can prepare for the right repair path.
Sandwich, Pizza, and Salad Prep Tables
True, Beverage-Air, Continental, Traulsen, Delfield, and Turbo Air sandwich, pizza, and salad prep tables share common failure modes: refrigerant loss, evaporator coil icing, condenser fan failure, dirty coils blocked by line traffic, and controller faults. Pan covers, night covers, and ambient kitchen temperature affect well performance.
Failures During Service
A prep table failing mid-service with prepared product on hand is an emergency intake. Document the well temperature, move the most temperature-sensitive product to backup refrigeration if available, and call the line so the request can be flagged.
Common Symptoms
- Prep well above 41°F with product on hand
- Rail not cooling, pans warming
- Refrigerated base cycling or warming
- Evaporator coil icing in the base
- Condenser fan failure or dirty coils
- Compressor short-cycling or not running
- Controller fault or temperature display error
What to Photograph
Photos sent at intake help the dispatched provider arrive prepared. Three categories help most:
- Equipment nameplate
- Well temperature display
- Failure point
What To Have Ready
- ›Brand and model from nameplate
- ›Sandwich, pizza, or salad prep configuration
- ›Number of pans / well length
- ›Current well and base temperatures, normal setpoint
- ›Service hours window
- ›COI, W-9, PO, or vendor onboarding requirements

What This Line Does Not Handle
Residential prep stations, food-truck mobile prep tables not built to commercial spec, and DIY parts-only requests.
Food safety. If product temperature is outside your facility's safe range, follow your internal food-safety plan, temperature log procedure, HACCP plan, insurance requirements, and local health department guidance. The request line can flag the repair as urgent and the dispatched provider can document repair actions and temperature recovery, but your facility is responsible for product handling, discard, and food-disposition decisions.
