What Does bAd LinE Error Mean on Samsung NE59R4321SS?

Error bAd LinE on Samsung NE59R4321SS: Incoming 240V power supply fault with one leg of the supply missing or below spe. Follow the troubleshooting steps below to diagnose and fix this range issue. The bAd LinE error on your Samsung NE59R4321SS range indicates the control board detected that one leg of the required 240V power supply is missing, low, or unstable. The range cannot operate safely on a partial supply. Start by fully tripping and resetting the double-pole circuit breaker for the range — a partially tripped breaker is the most common cause and the easiest fix. ## What Does bAd LinE Mean? A standard North American electric range requires a 240V supply consisting of two separate 120V legs from the electrical panel. The NE59R4321SS control board continuously monitors both legs and displays bAd LinE when it detects one leg is absent or below specification. The most common cause is a double-pole circuit breaker that has partially tripped. When only one pole of a double-pole breaker trips, the breaker handle may still appear to be in the ON position while only supplying power on one leg. This is a known characteristic of double-pole breakers and is fixed by physically moving the handle fully to OFF and then back to ON. Loose or burned wiring at the range’s terminal block — the connection point where the power cord meets the range — is the second most common cause. Terminal block connections can loosen over time from the thermal expansion and contraction that comes with a range’s heating and cooling cycles. ## Possible Causes 1. Double-pole circuit breaker for the range has partially tripped — appears ON but only supplying one leg of the 240V supply 2. Loose or burned wiring connection at the range’s terminal block — the power cord entry point at the rear of the range 3. Damaged power cord with a broken conductor on one of the hot wires 4. Power outage or surge that removed one phase of the household supply 5. Faulty or aged wall outlet or dryer-style receptacle with a burned contact on one side 6. Rare: a failed main control board incorrectly displaying bAd LinE when the supply voltage is correct ## Troubleshooting Steps | Step | Action | Expected Result | |------|--------|-----------------| | 1 | Locate the double-pole circuit breaker for the range in your electrical panel; move the handle firmly to the full OFF position, wait 30 seconds, then move it firmly back to ON | Partially tripped breaker is reset — bAd LinE may clear on power restoration | | 2 | Unplug the range, wait 1 minute, then plug it back in; this resets the control board and clears errors caused by transient power events | Control board resets — bAd LinE does not return if caused by a transient surge | | 3 | If you have a multimeter, measure voltage at the range outlet: between the red and black terminals you should read approximately 240V; between each hot terminal and the neutral terminal you should read approximately 120V; an asymmetric reading confirms a supply fault | Voltage measurements confirm a balanced 240V supply or identify the defective leg | | 4 | Disconnect all power and inspect the range terminal block (accessible from the rear panel): check for loose screws on the terminal connections, burned or charred wire insulation, and corroded contacts; tighten loose screws and replace damaged wiring | Terminal block connections are tight and undamaged | | 5 | Inspect the power cord along its full length for cuts, kinks, or damage; check the plug prongs for burn marks; replace a damaged power cord before reconnecting to power | Power cord is undamaged and plug prongs are clean | | 6 | If all wiring checks are correct and bAd LinE persists, contact a licensed electrician to verify the outlet and household panel wiring | Electrician confirms supply is correct — fault is in the range control board | If you measure voltage at the outlet and confirm one leg is missing or low, contact a licensed electrician to diagnose the household wiring. Do not attempt to repair household wiring yourself — it is a licensed trade requiring proper safety equipment. Do not use the range until the full 240V supply is confirmed. ## When to Call a Technician Contact Samsung authorized service if: - Voltage at the outlet is confirmed low or unbalanced — this is a household wiring issue requiring a licensed electrician, not a range repair

  • The outlet voltage is confirmed correct at 240V but bAd LinE persists after a power cycle — the main control board may be falsely detecting the error
  • You find burned wiring at the terminal block that requires professional repair Professional repair costs for bAd LinE issues typically range from $80 to $300 depending on the specific component and your service region. ## Frequently Asked Questions ### Why does my Samsung NE63A6511SS show bAd LinE after a power outage? Power outages frequently restore power with one phase returning before the other, or with a brief voltage imbalance as the grid stabilizes. The {model_display} control board detects this transient imbalance and displays bAd LinE. In most cases, fully tripping and resetting the circuit breaker for the range, combined with a 1-minute unplug, resolves the error after an outage.

Can a partially tripped breaker look like it is still ON? Yes, and this is one of the most confusing aspects of double-pole breakers. When one pole of a double-pole breaker trips while the other remains closed, the handle can sit in a mid-position that looks like ON. Moving the handle fully to OFF and then fully back to ON resets both poles simultaneously. This is the correct first step for bAd LinE.

Is bAd LinE dangerous — can I use any part of the range while it is showing? Samsung recommends not using the range while bAd LinE is active. A partial 240V supply can cause control board confusion and potentially damage internal components. Resolve the supply issue before using either the oven or the surface burners.

How do I know if the problem is in the range or in my home wiring? Test the voltage at the wall outlet with a multimeter. Measure between the red and black terminals — you should read approximately 240V. If one leg is missing or low, the problem is in the house wiring or panel, not in the range itself. If the outlet reads a correct balanced 240V and bAd LinE still appears after a power cycle, the range control board is the issue. Reference: Samsung official support documentation (samsung.com/us/support) and authorized service guides ### Is it safe to keep using my Samsung NE59R4321SS with error bAd LinE? If error bAd LinE does not indicate an immediate safety hazard such as a gas leak, electrical short, or water flooding, you can continue limited use while monitoring the appliance. However, running the range with an active error code increases the risk of further damage. Address the underlying issue as soon as possible. For high-severity errors, disconnect the appliance and contact a qualified technician. ### How much does it cost to fix error bAd LinE on a Samsung NE59R4321SS? Repair costs for error bAd LinE on the Samsung NE59R4321SS range depend on the root cause. DIY fixes such as cleaning filters, resetting the unit, or reconnecting loose wires cost nothing beyond basic tools. If a component replacement is needed, parts and labor from a certified technician are the main expenses. Contact a Samsung-authorized service provider for an accurate estimate based on your specific situation. ### What does error code bAd LinE mean on a Samsung range?
