First Co. units often use specific color codes for High (typically Black) and Low (typically Red) speeds; mixing these up can lead to poor performance or coil freezing. Diagnostic Check: While the motor is out, manually spin your blower wheels to check for balance. An unbalanced wheel is the #1 cause of premature bearing failure and excessive noise in new M35 installations.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eCross-Reference\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch3\u003e\u003cstrong\u003eFirst Co.
