Lennox Furnace Control Board and Circuit Board Troubleshooting in Greater Vancouver – Expert Repair Services by CANRO Heating & Cooling A Lennox furnace is built to provide reliable warmth and efficiency, even in Greater Vancouver’s cold, damp winters. At the heart of your furnace’s operation are two essential components: the control board and the circuit board. These components manage nearly every aspect of your furnace’s function, from the blower fan and ignitor to the gas valve and safety systems. When issues arise with the control board or circuit board, your furnace may experience a range of problems, from failing to ignite to short cycling and irregular heating.
CANRO Heating & Cooling specializes in Lennox furnace troubleshooting, repair, and replacement services across Greater Vancouver. Our skilled technicians have the expertise to diagnose and fix control board and circuit board issues, ensuring your furnace runs smoothly and efficiently.
Understanding the Role of the Control Board and Circuit Board in a Lennox Furnace
In a Lennox furnace, the control board and circuit board serve as the “brain” of the system. Here’s an overview of each component’s role and how they work together to keep your furnace running optimally.
1. Control Board The control board is a printed circuit board that coordinates the operations of your furnace. It sends signals to key components—such as the blower motor, ignitor, and gas valve—at precisely the right time to ensure proper heating. It also communicates with the thermostat, adjusting functions based on temperature settings.
2. Circuit Board The circuit board is often integrated with the control board in modern furnaces and handles the flow of electricity to various components within the furnace. It ensures that components receive power only when needed and protects the furnace from electrical overloads. If a circuit board fails, the furnace may not function properly, or certain parts may fail to activate.
Common Issues with Lennox Furnace Control Boards and Circuit Boards
Problems with the control board or circuit board can prevent your furnace from working effectively or even from turning on at all. Here are some common issues that indicate a problem with one of these essential components:
- Furnace Won’t Turn On: A malfunctioning control board may not send the signal to start the furnace, leaving your home cold and uncomfortable.
- Blower Fan Runs Continuously: A faulty control board can cause the blower fan to run nonstop, even when the furnace isn’t actively heating.
- No Ignition or Heat: If the circuit board fails to power the ignitor or gas valve, the furnace won’t produce heat.
- Short Cycling: When a control board malfunctions, it may cause the furnace to turn on and off frequently, which reduces efficiency and increases wear.
- Inconsistent or Inaccurate Thermostat Readings: A control board that’s out of sync with the thermostat can lead to inconsistent temperatures or difficulty maintaining a comfortable setting.
Troubleshooting Tips for Lennox Furnace Control Board and Circuit Board Issues
While some control board and circuit board problems require professional repair, you can try a few basic troubleshooting steps to check for minor issues. If these tips don’t resolve the problem, CANRO Heating & Cooling is here to help.
Step 1: Check the Thermostat
Ensure that your thermostat is set to “Heat” and the fan is set to “Auto” rather than “On.” A thermostat set to “On” may keep the blower fan running constantly, which can sometimes be mistaken for a control board issue.
Step 2: Reset the Furnace
Many modern Lennox furnaces have a reset switch. Turn off the power to the furnace at the breaker, wait a few minutes, and turn it back on. This can sometimes clear temporary control board glitches.
Step 3: Check for Error Codes
Some Lennox furnaces have LED lights on the control board that flash
error codes when there’s a problem. Consult your furnace manual or contact CANRO Heating & Cooling for assistance in interpreting these codes.
Step 4: Inspect the Circuit Breaker and Fuse
A tripped circuit breaker or blown fuse may cut power to the control board and circuit board, preventing your furnace from turning on. Reset the breaker or replace the fuse if necessary.
