Maytag Refrigerator MSD2957AEB Won't start or doesn't start

Adaptive defrost control board.

This thermal overload protector helps prevent motor overheating by interrupting power when temperatures exceed safe limits. It restores normal operation once the motor cools, protecting the appliance from damage and reducing risk of failure. What it does:

• Senses excessive motor temperature and interrupts current to stop the motor from running when overheated
• Helps prevent motor burnout and related electrical damage
• Can resolve symptoms such as a dryer or washer motor that stops mid-cycle, won't start, or trips the circuit during heavy use
• Works as a safety device in the motor circuit rather than a control or relay

• One thermal overload protector

• Disconnect power before accessing or replacing the motor overload; follow appliance-specific service manual steps
• Handle terminals and wiring carefully; replace using the same connections and orientation as the original
• If the motor repeatedly overheats after replacement, inspect motor bearings, venting, or other causes rather than replacing overload repeatedly
