Laars Heating Systems 2400-228 Pressure Switch
The Laars Heating Systems 2400-228 Pressure Switch is a critical safety component designed for precise draft monitoring and combustion air verification in high-efficiency hydronic systems. This OEM replacement part, also identified as the Pressure Switch Mark II, is engineered specifically for compatibility with Laars Mark II H-Series residential and commercial boilers, including models H, HW, and HP (sizes 60-130). As a normally open switch, it ensures the inducer motor is generating sufficient static pressure to vent flue gases safely before allowing the ignition sequence to proceed.
Constructed for heavy-duty furnace troubleshooting and industrial reliability, the 2400-228 features a robust internal diaphragm calibrated to react to minute pressure differentials. Integrating this boiler safety switch into your service routine prevents common issues such as ignition failure, short cycling, and system lockouts caused by inadequate venting or blocked heat exchangers. Its direct-fit design simplifies installation for field technicians, ensuring the system maintains 95% AFUE performance standards while protecting against dangerous flue gas accumulation.
Key Benefits
- Direct OEM Compatibility: Specifically engineered for Laars Mark II H, HW, and HP series boilers to ensure exact set-point accuracy.
- Venting Safety: Acts as a primary combustion airflow sensor, preventing the gas valve from opening if the exhaust path is obstructed.
- Durable Construction: Built with high-grade materials to withstand the thermal cycling and humidity typical of hydronic heating systems.
- Precise Calibration: Factory-set to ensure the boilers operate within safe pressure parameters, reducing nuisance service calls.
Common Questions
What are the symptoms of a failing Laars 2400-228 switch?
Common signs include the inducer motor running continuously without the igniter glowing, or the control board displaying a specific pressure switch lockout code. Verify with a manometer to ensure the static pressure meets the switch requirement before replacing.
Can I use this switch for different Laars models?
This part is specifically cataloged for the Mark II H-Series (Sizes 60-130). For Mighty Therm or NeoTherm units, please verify the specific SKU as pressure set points vary significantly between models.
Does this switch come with the replacement tubing?
This SKU typically includes the pressure switch assembly itself. It is recommended to inspect existing silicone pressure tubing for cracks or moisture buildup during installation to ensure accurate sensing.
This item is not eligible for free shipping.
