Possible Causes
Incorrect line voltage (e.g., 120 V instead of 240 V), Loose power cord connections, Faulty terminal block on range
How to Fix / Troubleshooting
Safety First: This involves live 240 V circuits. If you are not trained, contact an electrician or appliance technician.
- Verify supply voltage: With a multimeter and proper safety precautions, measure voltage at the range receptacle or terminal block. Danby electric ovens typically require 240 V (or 208 V in some regions).
- Inspect terminal block: Disconnect power, remove the rear cover at the cord entry, and inspect the terminal block for burnt lugs or loose screws. Tighten connections and replace a damaged terminal block.
- Check cord: Inspect the power cord for burns, cracks, or loose strain relief. Replace if damaged.
- Control board: If supply voltage is correct and wiring is sound, the control board's power supply circuit may be faulty and require replacement.
