# Monogram oven: Bad Line means the electrical supply is not what the oven expects

### What the appliance is actually doing

A supply problem rather than an appliance one: the oven is reporting that the electrical line feeding it is not what it should be.

### Which machines this one applies to

Monogram professional ranges and wall ovens. Monogram says plainly on their own range and oven table that they cannot list every code for every model past and present, so a code missing from their table is not proof that your appliance cannot raise it — and a code in it is not proof that yours can. The model number settles it.

### What to do about it

- Check the breaker. A double-pole breaker with one side tripped gives an appliance half of what it expects and produces exactly this.
- Note whether anything else in the house is behaving oddly at the same time.
- This is an electrical investigation rather than an appliance repair, and it should be treated as one.

### Where this goes next

The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and every one of those pages carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 614-3572](tel:+13056143572) and describe what the display is doing before booking anything.
