Possible Causes
Failed microcontroller or power supply on PCB, Burnt relay contacts, Surge-damaged components, Cracked solder joints on high-current paths
How to Fix / Troubleshooting
Safety: Disconnect the appliance from mains before accessing the control board.
- Locate the main PCB: On most Teka freezers, it is behind a rear metal or plastic cover or in a top control housing.
- Visual inspection: Look for burnt areas, swollen capacitors, or broken tracks. Smell for burnt electronics.
- Check connectors: Reseat all plugs to ensure solid contact. Inspect for heat-discolored terminals.
- Verify supply voltage: With extreme caution and only if you are trained, you can measure input voltage to the PCB when powered. Otherwise, leave live testing to a professional.
- Board replacement: If E7 persists after power-cycling and no external components are faulty, replace the main PCB with the exact Teka part number. Transfer any configuration jumpers or wiring positions exactly.
Test: After replacement, restore power, set the desired temperature, and monitor operation for several hours to confirm stable cooling and no E7 code.
