Job Checkin

Service call that the Propane Fired Furnace was not working properly. Upon arrival, spoke with Homeowners about issue, who informed me that the Furnace was Flashing a 3 Flash Code. Proceeded to the Furnace to troubleshoot. Confirmed the Error Code and cycled System to test. Inducer Motor was running but the Pressure Switch was not closing. Found an old Bees nest in the Intake Pipe near the Furnace. Removed obstruction and Measured Pressure across the Switch which was reading around 1.6" WC. The Pressure Switch is rated for 1.4" WC. After the Inducer Motor ran for several minutes it began collecting water and the Pressure dropped. Removed Drain Tubing and cleaned. Checked Pressure Switch Tubing Lines as well to ensure they were cleared. With the system operating, the Pressure across the Switch remained at 1.6" WC, fluctuating Up and down slightly. Removed Draft Inducer Motor to inspect. Resealed and reconnected Motor. Performed Combustion Analysis On Furnace while measuring the Outlet G
