Lennox furnace watchguard error
The Lennox furnace watchguard error can sneak up at any time, but it is most common in the winter when the furnace is running low on gas and needs restarted.
The Lennox furnace watchguard error occurs when the system detects that one or more of the monitored sensors are not responding to commands. The system will display an error code and shut off power within seconds of detecting this problem.
This article explains a detailed procedure for troubleshooting this issue, how you can fix it yourself if you want to save some money, and what owners should consider doing if they want a professional service done first.
A Lennox furnace watchguard error is a problem with the furnace’s hub. When the furnace detects a low-pressure alarm, the automatic system engages and closes down an exhaust port.
A Lennox furnace watchguard error is a problem with the furnace’s hub that causes it to trigger an auto-shutdown of the exhaust port when the pressure drops below certain values. This auto-shutdown requires a technician to manually reset the sensor to restore normal operation.
Lennox’s PowerGuard™ Gas Furnace WatchGuard™ Sensor automatically detects when the pressure drops below three psi (or 0.25 bar) and shuts down gas flow to prevent overloading your home’s system in damage or injury.
Lennox furnace WatchGuard error is a malfunction caused by the Lennox furnace. The cause of the problem is unclear, but it can happen as early as three years after installation.
Since it can happen at any time, it is important to keep in touch with the warranty and maintenance logs to report problems promptly.
