Possible Causes

Tripped house breaker, Loose or burned power connections at terminal block, Failed electronic control board, Open thermal fuse (if equipped)

How to Fix / Troubleshooting

Safety first: High voltage is present at the terminal block. Turn off the breaker and verify with a meter before touching wiring.

  • Check breaker: Verify the oven's double-pole breaker is ON and not tripped. Reset if necessary.
  • Test incoming power: At the oven's rear terminal block, confirm proper voltage (typically 240 VAC across L1–L2 and 120 VAC from each leg to neutral). If missing, the issue is in the house wiring.
  • Inspect terminal block: Look for burned wires or melted plastic. Repair wiring and replace the terminal block if damaged.
  • Check thermal fuse: Some Monogram ovens have a thermal cutoff fuse in series with the control. Test for continuity and replace if open.
  • Control board: If power and fuse are good but the display is dead, replace the electronic oven control board or display board as applicable.
