Gone are the days when a furnace was a simple piece of equipment that required minimal maintenance. Nowadays, furnaces come with advanced technology, such as circuit boards, that can be challenging to repair or replace if something goes wrong. In this article, we will look at the 1170063 circuit board wiring diagram for Honeywell gas furnaces, which will help you understand the wiring system and make any necessary repairs.
What is the 1170063 Circuit Board?
The 1170063 circuit board is an essential component of a Honeywell gas furnace. It controls the furnace’s operation, including ignition, fan speed, and safety features. The circuit board also monitors the furnace’s performance and detects any issues that may occur.
A faulty circuit board can cause the furnace to malfunction or stop working altogether. Therefore, it’s crucial to understand the wiring diagram to diagnose and repair any problems with the circuit board.
How Does the 1170063 Circuit Board Work?
The 1170063 circuit board has several components that work together to control the furnace’s operation. These include:
| Component | Description |
|---|---|
| Transformer | Converts high voltage to low voltage for the circuit board |
| Relays | Control the furnace’s operation, such as ignition and fan speed |
| Sensors | Detect the furnace’s performance, such as temperature and pressure |
| LED Indicator Lights | Show the furnace’s status and any error codes |
The circuit board receives input from the thermostat and other sensors to determine when to turn on and off the furnace. If there is an issue, the circuit board will display an error code on the LED indicator lights, which can help diagnose the problem.
Wiring Diagram for the 1170063 Circuit Board
The wiring diagram for the 1170063 circuit board can be complex, but understanding it is essential to diagnose and repair any problems. The diagram consists of several parts, including:
- Transformer
- Relays
- Inducer Motor
- Gas Valve
- Limit Switch
- Pressure Switch
- Thermostat
Each component must be wired correctly to ensure proper function of the furnace. Here’s a breakdown of how each component should be wired:
Transformer
The transformer connects to the circuit board and converts high voltage to low voltage, which the circuit board uses. The transformer has two wires, one red and one blue, that connect to the circuit board.
Relays
The relays control various functions of the furnace, such as ignition and fan speed. There are typically four relays, and each relay should be wired correctly to ensure the furnace’s proper operation.
Inducer Motor
The inducer motor is responsible for removing fumes and other gasses from the furnace. It connects to the circuit board and should be wired correctly to ensure proper operation.
Gas Valve
The gas valve controls the flow of gas to the furnace burners. It connects to the circuit board and should be wired correctly to ensure the furnace’s proper operation.
Limit Switch
The limit switch is a safety feature that shuts off the furnace if it becomes too hot. It connects to the circuit board and should be wired correctly to ensure proper operation.
Pressure Switch
The pressure switch is another safety feature that detects when there is a pressure issue in the furnace. It connects to the circuit board and should be wired correctly to ensure proper operation.
Thermostat
The thermostat is the device that controls the furnace’s temperature. It connects to the circuit board and should be wired correctly to ensure proper operation.
