- Restores Full Heater Operation — A functioning control box governs burner ignition, temperature regulation, and operational sequencing; a failed unit can leave the heater completely inoperable on the jobsite.

The control box is the central electrical hub of the HDR 155 Direct Fired Radiant Heater, managing ignition sequencing, burner operation, and safety shutoff functions. It receives input signals from the thermostat and safety sensors, then directs the heater to fire, modulate, or shut down accordingly. When the control box fails or develops a fault, the heater may refuse to ignite, cycle erratically, or fail to respond to temperature controls — making prompt replacement essential for maintaining heat output on cold-weather worksites.
