Heat Controller MARS-10586 Furnace Blower Motor 1/3 Hp

Product Description

The HEAT CONTROLLER MARS-10586 is a three-speed, direct drive furnace blower motor rated at 1/3 HP, 208-230 volts, and 1075 RPM. Built for standard efficiency residential and light commercial forced-air heating systems, it features an open air-over enclosure with all-angle sleeve bearings for reliable continuous fan duty operation. Class B insulation and thermal overload protection are built in, providing a layer of defense against overheating during sustained operation. The motor ships with 2.25-inch resilient rings for base mounting and includes 26-inch and 30-inch leads to accommodate common wiring configurations in furnace blower compartments.

This motor is suited for direct drive blower applications in gas, oil, or electric forced-air furnaces where a 5.5-inch frame motor is specified. Its electrically reversible design allows the installer to match airflow direction to the equipment requirement without sourcing a separate model. Single-phase, 60 Hz operation makes it compatible with standard North American residential and light commercial electrical supply. Licensed HVAC technicians and mechanical contractors typically handle installation as part of a blower motor replacement or furnace repair service call.

Key Features

• Three-speed operation for flexible airflow matching across heating and cooling modes
• Electrically reversible rotation eliminates the need for separate CW and CCW motor SKUs
• 2.25-inch resilient rings included for base mounting — no separate hardware required
• All-angle sleeve bearings support a range of mounting orientations
• Class B insulation with thermal overload protection for continuous fan duty use
• 26-inch and 30-inch leads provided to fit common furnace blower deck wiring layouts

Compatibility

Designed as an OEM-style direct drive replacement blower motor for residential and light commercial forced-air furnaces calling for a 5.5-inch frame, 1/3 HP, 208-230V, 1075 RPM, three-speed motor.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out all electrical power to the furnace before removing the existing motor or making any wiring connections. Verify that supply voltage and speed tap wiring match the equipment wiring diagram before energizing. Secure the resilient mounting rings firmly before startup to prevent vibration-related noise or movement.
