The prices of circuit boards depend on the brand and the model of the furnace, and they typically range from $51.15 to $357.29 as of 2015. Some online retailers, such as RepairClinic.com, offer multiple options at different prices, including OEM and non-OEM models.
The more expensive circuit boards normally include a kit that contains the necessary harness for installation and replacement. They also feature a communication functionality that allows customers to access the system status, diagnostics and controls of the circuit board remotely. Some circuit boards, such as the S9200U1000 model intended for Amana, Lennox and Goodman furnaces, feature a system that monitors the flame presence, pressure switch and temperature limit.
