Maytag Dryer Error Code Lo

The Lo code means the dryer's control board has detected incoming voltage below 90 VAC for 8 consecutive seconds. This threshold is the minimum voltage required for safe dryer operation. The code is designed to protect the appliance from running on insufficient power, which could damage motors and electronic components. In most cases, the problem originates with the home's electrical supply rather than the dryer itself.

No, you should not attempt to run the dryer while the Lo code is active. Operating the dryer on insufficient voltage can overheat motors and other components, potentially causing further damage to the appliance or creating a fire hazard. Resolve the underlying power supply issue before resuming use.

Repair costs vary widely depending on the root cause. If the fix is a tripped breaker reset, there is no cost involved. Outlet replacement or wiring repairs by an electrician typically range from $75 to $250 or more depending on the complexity. If the dryer's control board requires replacement, parts and labor can range from $150 to $400 or higher. Getting a diagnosis before committing to repairs is recommended since many Lo code cases are resolved through electrical supply corrections rather than dryer part replacement.

Start by checking your circuit breaker panel for a tripped or partially tripped breaker and reset it if needed. Next, use a multimeter to measure the voltage at the dryer's wall outlet to confirm it is at or above the required level. If voltage is low at the outlet, the issue likely lies with household wiring or the utility supply, and an electrician should be consulted. If outlet voltage is correct, inspect the dryer's power cord and terminal block connections for any looseness or damage.

Simply resetting or unplugging the dryer will not permanently clear the Lo code if the underlying low voltage condition still exists. The control board will detect the low voltage again within 8 seconds of operation and re-trigger the code. The code will only stay cleared once the incoming supply voltage is restored to an adequate level.
