you restore precise pressure regulation and flow control

Most failures are secondary shorts caused by a grounded contactor coil or a pinched thermostat wire

Blower wheels must match the original dimensions (10-inch diameter by 6-inch width) and bore size exactly to maintain the designed air volume and prevent interference with the blower housing walls

Designed for industrial and commercial heating applications

a faulty limit switch is a common cause of furnace short-cycling and should be tested if the heat exchanger is not genuinely overheating
