Maytag Dryer Error Code 3

Error code 3 means the control board detected an invalid state in the door sense circuit for more than 256 milliseconds. The door sense circuit is responsible for telling the control board whether the door is open or closed. When that signal is neither a clean open nor a clean closed for too long, the dryer stops and displays error code 3.

No. When error code 3 is active, the dryer halts operation because it cannot confirm a valid door state. Running a dryer with an uncertain door circuit could mean the drum runs with the door open, which is a safety risk. Do not attempt to bypass the error. Resolve the door sense circuit fault before resuming use.

Yes. A loose or open wire terminal in the door sense circuit is the most common cause of error code 3. Even a partially seated terminal can produce an intermittent signal that the control board reads as an invalid state, triggering the error. Always check wire connections before replacing any parts, since this fix costs nothing and takes only a few minutes.

Start by unplugging the dryer and inspecting all wire terminals in the door sense circuit for looseness, corrosion, or disconnection. Reconnect or reseat any suspect terminals and power the dryer back on to see if the code clears. If the error returns, test the door switch with a multimeter for continuity in both the open and closed positions. A switch that fails this test needs to be replaced. If the switch tests fine, inspect the wiring harness between the switch and control board for damage.

If the fix is simply reseating a loose wire terminal, there is no parts cost and the repair takes only minutes. A replacement door switch typically costs between $15 and $40 for the part. If a technician is needed, expect a service call fee of $75 to $150 plus labor, bringing the total to roughly $100 to $200 depending on your area. A control board replacement is the most expensive possibility, with parts ranging from $100 to $250.
