Frequently asked questions

Common questions about A.O. SMITH from 3G Electric.

What types of A.O. Smith limit switches are available through 3G Electric?

3G Electric supplies A.O. Smith limit switches, such as the 100110072 model, which are used as limit controls in HVACR systems. These switches are designed to open or close electrical circuits based on temperature or pressure thresholds, providing safety and operational control. They are typically rated for specific voltage and current levels and are compatible with various furnace and boiler configurations.

Are A.O. Smith heater elements compatible with 480 V systems?

Yes, A.O. Smith heater elements, such as the 100110133 and 100111570 models, are available with a voltage rating of 480 V. These elements are used in electric heaters and heat exchangers for HVACR applications. They are designed to provide consistent heat output and are direct replacements for OEM parts in compatible equipment.

Can A.O. Smith blower assemblies be used with Lochinvar equipment?

Yes, A.O. Smith blower assemblies, such as the 100110631 model, are compatible with Lochinvar brand equipment. These assemblies operate at 120 V AC and are used as draft inducers in furnaces and boilers. They are designed to meet OEM specifications for airflow and mounting, ensuring proper combustion and system efficiency.

What is the function of an A.O. Smith blower pressure switch?

An A.O. Smith blower pressure switch, such as the 100109962 model, monitors air pressure in the venting system of a furnace or boiler. It ensures that the draft inducer is operating correctly before allowing the burner to ignite. If pressure is insufficient, the switch prevents operation, enhancing safety and preventing incomplete combustion.

Are A.O. Smith pilot assemblies available for different furnace models?

Yes, 3G Electric stocks multiple A.O. Smith pilot assemblies, including models 100109926 and 100109295. These assemblies are used to ignite the main burner in gas-fired furnaces and boilers. They are designed to fit specific OEM configurations and are available for various voltage and gas type requirements.

What specifications should I check when ordering an A.O. Smith burner assembly?

When ordering an A.O. Smith burner assembly, such as the 100110704 model, verify the manufacturer part number, product type (burner assembly), and compatibility with your equipment brand and model. Check the fuel type (natural gas or propane), input rating (BTU/hr), and mounting dimensions to ensure proper fit and performance.
