What BadLine Means
Whirlpool documents the Bad Line display as power being applied but not wired correctly. On a range that is a supply-wiring message: the appliance is receiving power in a way the control does not accept, typically a miswired terminal block or a missing neutral or ground connection.
Common Causes of BadLine
- Terminal block wired incorrectly at installation
- Missing or loose neutral or ground connection
- Outlet wired incorrectly
- Damaged supply cord or connection
🔧 One Safe Check You Can Try
There is nothing to fix at the panel and this is not a code to work around. Switch the range off at the breaker. If the range was recently installed, moved, or had work done on its outlet or terminal block, that is almost certainly the cause and it must be corrected by a qualified electrician or the installer - not by re-seating the plug and hoping. Incorrect supply wiring on a 240 volt appliance is a shock and fire risk, so leave the breaker off until it has been checked.
⚠ Why You Shouldn't Go Further Than That
- This is a 240 volt supply fault - electrician territory, not owner territory.
- Working on the terminal block of a live range is genuinely dangerous.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
