Gas Unit Heater Replacement Parts
Gas-fired unit heaters use a combination of ignition, airflow, gas control and safety components to operate properly. When servicing an existing heater, replacement parts should be matched to the equipment manufacturer, model and original part number whenever possible.
Common unit heater replacement parts include:
Control boards and ignition controls
Gas valves and gas control components
Blower and fan motors
Fan blades and propellers
Power venters and draft inducer assemblies
Igniters and electrodes
Flame sensors
Pressure switches
Limit and temperature switches
Transformers, relays and electrical controls
Unit Heater Control Boards & Ignition Parts
Control boards and ignition components manage important operating functions within compatible gas unit heaters. Available replacement components include ignition control boards, ignition modules, igniters, electrodes, flame sensors and related electrical controls.
When replacing a control board or ignition component, verify the heater model and original manufacturer part number. Manufacturers may revise or supersede components over time, so a current replacement part may differ in appearance from the original while remaining the specified replacement.
Unit Heater Motors, Fans & Draft Inducers
Unit heater airflow components include blower motors, fan motors, fan blades, propellers, power venters and draft inducer assemblies. These components should be selected according to the heater model and manufacturer specifications to ensure the correct electrical requirements, rotation, mounting and performance.
For replacement motors and fan assemblies, verify the original part number and equipment model before ordering whenever possible.
Unit Heater Gas Valves, Pressure Switches & Safety Controls
Gas valves, pressure switches, limit switches and other safety controls are designed for specific heater operating requirements. These components play important roles in controlling fuel flow, monitoring operating conditions and maintaining the heater's designed sequence of operation.
Replacement controls should match the specified manufacturer part number or approved replacement for the unit heater being serviced.

Finding the Correct Unit Heater Part
The most reliable way to identify a replacement unit heater part is to locate the equipment model and serial information along with the part number from the existing component whenever available.
Search by the manufacturer's part number or heater model rather than relying only on the appearance of the component. Parts that look similar may have different electrical ratings, dimensions, operating specifications or equipment compatibility.
If an original component has been discontinued or superseded, review the current manufacturer replacement information and product specifications before ordering.
