Key Features
- Genuine OEM Electrical Specification — Matched to the correct coil voltage, contact rating, and switching capacity required by the Arctic Bear HD heater control circuit.
- Direct Drop-In Replacement — Engineered to the original terminal layout and mounting footprint for a straightforward swap in the heater's electrical panel.
- Broad Arctic Bear HD Fitment — Compatible with both the Arctic Bear HD Natural Gas (5000620199) and Diesel (5000620197) indirect mobile air heater models.
- Consistent Heater Operation — A functioning relay ensures the burner and control systems switch on and off correctly, maintaining steady heat output on cold-weather jobsites.
- Fuel System Safety Compliance — As a switching component in the burner control circuit, using the correct OEM-rated relay helps maintain safe, code-compliant operation of the combustion system.
A relay is an electrically operated switch that controls high-current circuits — such as the burner ignition or fuel valve — using a low-current signal from the heater's control board. In an indirect air heater like the Arctic Bear HD, the relay acts as the gatekeeper between the control logic and the components that generate heat, ensuring each stage of the heating cycle fires in the correct sequence. When a relay fails or develops a faulty contact, the heater may fail to ignite, cycle erratically, or shut down entirely, interrupting heat delivery and making diagnosis difficult without replacing the suspect component first.
