HVAC & Furnace Circuit Boards

The HVAC circuit board, also called the control board, in your furnace is the brain of your heating system. This component tells the entire model what it should do to circulate heat or cool air around your home. Different sizes can determine durability and age because smaller boards tend to have weaker material. Knowing the components and their model number can allow you to repair or replace any control board in a short amount of time.

How Does A Furnace Control Board Work?

Furnaces use circuit boards to perform many activities, from alerting you to unit problems to igniting your heating system. It controls ignition, flame sensing, thermostat settings, gas valve adjustment, and blower motor speed. You can prevent buildup and protect any home or workplace from electric accidents.

In an ideal world, the board matches the central furnace's lifetime not to necessitate replacement. Nevertheless, furnaces can fail, and you must be prepared for repairs. If you have the components for repair, the control board can resume necessary functions.

Furnace Circuit Board Replacement Parts

At Furnace Part Source, we offer a range of circuit boards from the best-name brands in the industry. Browse our selections and see which models are suitable for your heating system. Take advantage of available discounts and shipping deals.

The circuit board within your furnace is the system that initiates and ends the heating process when you're trying to achieve a specific temperature in your home. It also monitors the temperature to make sure that the model doesn't overheat and alerts you to any potential problems that you might have with your machine.

Carrier Furnace Circuit Board

Carrier furnaces are designed to run quietly and conserve energy to provide the utmost convenience. Circulate air and control humidity with ease. Insulation provides noise control while reducing the amount of wasted energy that would escape the system.

The HK38EA022 Circuit Board is meant for defrost control and is OEM-certified. It can fit specific Carrier, Bryant, and Payne furnace systems while replacing the HK38EA005 part in furnace systems.

Lennox Furnace Circuit Board

When you buy Lennox, you buy quality for any furnace or cooling operation. The company developed the first steel-riveted furnace in 1895. The company aims to reduce operating costs for the HVAC system user while increasing comfort in an enclosed home or residence.

One good example of Lennox's craftsmanship is the 63W36 Circuit Board. This is meant for heat pump control in the 102791-01 system.

Furnace Control Boards From Honeywell

Business executives and engineers want to create a sustainable future with their gas furnaces and heating systems. The creator of the furnace regulator, Honeywell, focuses on designing products for the future. Each product aims to operate with energy efficiency. Each innovation optimizes safety and efficiency. With each new furnace system, the company has committed to reducing greenhouse emissions and potential hazards.

In line with such lofty goals, Honeywell circuit boards reflect the same commitment to efficiency and safety. Even rarer items, such as the Honeywell #ST9103A1002 Circuit Board fan replacement, reflect these properties. This fan can be fixed or field-adjustable with a combustion air blower and primary oil control.
