Display coolers sell product. When they run warm, fog up or go dark, sales drop and product spoils. J and G Refrigeration repairs display coolers and merchandisers for grocery stores, convenience stores, bakeries, delis and restaurants across Rockford and Northern Illinois.
From single-door beverage merchandisers to curved-glass deli cases, we repair the refrigeration, fans, heaters and lighting that keep your display working.
Signs You Need Display Cooler Repair
- Product on top shelves warmer than bottom
- Glass doors constantly fogged
- Lights flickering or out
- Compressor runs nonstop
- Water pooling under or inside the case
Common Problems We Fix
Case not holding temperature
Dirty condenser coils, low refrigerant or failed fans are common causes.
Fogging or sweating glass
Anti-sweat heaters and gaskets keep glass clear. When they fail, product disappears behind fog.
Lights out
Ballasts, LED drivers and wiring problems leave product in the dark.
Uneven temperatures
Blocked air flow from overstocking or failed fans create warm spots.
Water under the case
Drain problems are messy and unsafe.
