Opener displays E13; door may move a short distance then stop; unit may feel very hot to the touch.

Safety first: Do not attempt to cool the motor with water or spray. Allow natural cooling.

• Step 1 – Allow cooling period: Leave the opener powered but unused for at least 30–45 minutes to allow the internal thermal protector to reset.
• Step 2 – Reduce usage: Avoid repeated rapid cycling of the door. B&D openers are designed for a limited number of operations per hour.
• Step 3 – Improve ventilation: Ensure the opener head is not covered by insulation or stored items and that air can circulate around it.
• Step 4 – Check door balance: A heavy or unbalanced door forces the motor to work harder. Test door balance manually and have springs adjusted by a professional if needed.
• Step 5 – Motor health: If E13 occurs frequently under normal use and with a well‑balanced door, the motor windings may be deteriorating. Have a technician test and replace the motor assembly if necessary.
