Maytag Dryer Error Code Lo.U

Lo.U means the dryer's control board detected incoming AC voltage below 90 volts for 8 consecutive seconds. The dryer stops operation to protect itself from damage caused by low voltage conditions. This fault points to the electrical supply rather than an internal dryer failure in most cases. Checking the voltage at the outlet and circuit breaker is the correct first step.

No, it is not recommended to continue operating the dryer while this fault is active. Low voltage conditions can cause motors and heating elements to draw excessive current, leading to overheating and potential component damage over time. The dryer's control system triggers this fault specifically to prevent that kind of harm, so the underlying power issue should be resolved first.

Resetting the dryer by unplugging it or cycling the breaker may temporarily clear the Lo.U code, but the fault will return if the underlying low-voltage condition has not been corrected. The control board monitors voltage continuously, so any sustained drop below 90VAC for 8 seconds will trigger the code again. A reset is useful for confirming whether the issue was momentary, such as a brief utility sag, but it is not a fix for a persistent supply problem.

Some causes are DIY-friendly, such as tightening a loose power cord connection or checking whether the circuit breaker has partially tripped. However, if the issue involves wiring inside the breaker panel or the utility supply, a licensed electrician should handle the repair. Measuring voltage at the dryer outlet with a multimeter is a safe starting point for any homeowner comfortable with basic electrical checks.

If the problem is a failing circuit breaker, replacement typically costs between $150 and $300 including an electrician's labor. A loose or damaged power cord can be fixed for $20 to $75 in parts, often without professional help. If the control board is ultimately the cause, board replacement can range from $150 to $400 depending on the model and labor rates in your area.
