Arrived on site customer stated he started smelling a burning smell and shut off the thermostat to the master bedroom. However, the thermostat outside the room wired to the same system was still on. Tested voltage on transformer and measured 24V. Jumped R to G for fan and the blower motor was not running. Measured 120 volts at power plug to motor and noticed burn marks on the ground pin to the motor. Advised homeowner that his blower motor has burnt out and this could be due to either a power surge or a lack on return air. Unit shut off at outdoor breaker to prevent damage to the system. System is under parts and labor warranty. Parts are being shipped and will arrive Friday afternoon. Window unit delivered to customer.
