GE Oven Error Code LOW POWER

The LOW POWER error means the oven's control board has detected that the voltage between L1 and L2 at power-up is below 150VAC, which is insufficient for safe and normal operation. A standard 240VAC electric oven requires both legs of a split-phase circuit to be fully functional. The oven will not operate normally until the supply voltage is restored to an acceptable level. This is most often caused by a tripped circuit breaker or a wiring issue rather than a defective oven component.

No, you should not attempt to use the oven while this error is active. Insufficient voltage can cause heating elements and motors to draw excessive current as they work harder to compensate, which can damage components or create a fire hazard. The oven's control system displays this error specifically to prevent operation under unsafe electrical conditions. Address the power supply issue before using the appliance.

If the cause is a tripped breaker, there is no repair cost. If a licensed electrician is needed to diagnose and repair faulty home wiring or a damaged terminal block, expect to pay somewhere in the range of $100 to $400 depending on the extent of the work. If the control board itself is determined to be the fault after supply voltage is confirmed correct, board replacement typically costs in the range of $150 to $400 including parts and labor.

Start by checking the oven's dedicated circuit breaker in your home's electrical panel and reset it if it has tripped. Then use a voltmeter to measure the voltage at the oven's terminal block, confirming L1-L2 reads close to 240VAC. If voltage is low or missing on one leg, the problem is in your home's wiring or utility supply and may require a licensed electrician. Only if supply voltage is confirmed normal should you investigate the oven's internal components or control board.

Resetting the oven by cycling the breaker will clear the error temporarily, but the code will return at the next power-up if the underlying voltage problem has not been corrected. The control board checks L1-L2 voltage every time the oven is powered on. A permanent fix requires restoring proper 240VAC supply to the unit.
