The Wacker Neuson Thermostat is a genuine OEM component designed for HI750GM, HI900DGM, and CUB700GM series indirect-fired air heaters. As a direct factory replacement, this thermostat restores precise temperature regulation to your heater, ensuring consistent and controlled heat output in demanding jobsite conditions. It is verified to fit multiple HI750GM and HI900DGM configurations, including surge brake and mobile variants, as well as the CUB700GM diesel indirect-fired heater with genset.
Key Features
- Genuine OEM Temperature Accuracy — Manufactured to Wacker Neuson's exact switching tolerances, so your heater cycles on and off at the correct temperature set points rather than running hot or cold.
- Drop-In Replacement — Matches the original mounting configuration and electrical connection for a straightforward swap without additional hardware.
- Broad HI-Series Fitment — Confirmed for HI750GM, HI750GM HD, HI900DGM, and CUB700GM indirect-fired air heater models, covering both standard and surge-brake-equipped units.
- Protects Heat Exchanger and Burner Components — A correctly functioning thermostat prevents overheating cycles that can stress the heat exchanger and shorten burner service life.
- Fuel System Safety Compliance — In indirect-fired heaters, the thermostat is part of the fuel-cycle control circuit; using a correctly rated OEM part helps maintain safe operating limits as designed.
The thermostat in an indirect-fired air heater monitors the internal temperature of the heater unit and signals the burner to cycle on or off in order to maintain the target output temperature. When it functions correctly, the heater delivers steady, controlled warmth without overheating or short-cycling. A failed or out-of-spec thermostat can cause the heater to run continuously at unsafe temperatures, fail to reach operating temperature, or shut down unexpectedly — all of which interrupt heating on cold-weather worksites where consistent heat output is critical.
