Garland Commercial Oven Error Codes — What They Mean
Garland (a Welbilt brand) manufactures commercial ranges, convection ovens, and deck ovens for professional kitchens. Electronic Garland convection ovens display fault codes on the control panel.
| Code | Meaning |
|---|---|
| E1 | Cavity temperature sensor fault |
| E2 | High temperature safety trip |
| E3 | Ignition failure (gas models) |
| E4 | Blower / fan motor fault |
| Er | General control error |
Most Common Garland Oven Codes and Fixes
E1 — Temperature Sensor
Test the cavity sensor resistance or thermocouple output. Open circuit or out-of-range reading = replace sensor. Use Garland OEM sensor for correct calibration.
E2 — High Temperature
The oven temperature exceeded the safety threshold. Check thermostat setting, high-limit cutout continuity, and gas valve closure. Do not use until the root cause is identified.
E3 — Ignition Failure
Check gas supply is on and at correct pressure. Test the igniter spark gap and electrode condition. Verify the gas valve opens on call for heat. Check flame sensor rod for carbon deposits.
E4 — Fan Fault
Convection blower motor failure or obstruction. Remove any obstructions from the blower wheel. Check motor windings and run capacitor.
Er — General Error
Power cycle the oven. If Er persists, the control board has an internal fault. Contact Garland service.
