Cleaned blower wheel, housing and motor. BLOWER MOTOR COULD FAIL AT ANY MOMENT. System is currently operational, observed fan operation for over 20 minutes while cleaning up and writing invoice and fan continued to perform as designed. Operational amp draw is elevated on blower motor 5.9 / 6.8 but below listed RLA. Fan and blower were extremely dirty, parts of a filter were found in the wheel. Cleaned with detergent and brushed dry the motor and blew dust out with air compressor. Photos attached.
