Why Does Your Furnace Have a Pressure Switch? The pressure switch is a vital component in your home's furnace, serving as both a proving switch and a safety device. It works in tandem with the inducer motor to ensure that harmful combustion gases are being safely vented out of your home through the flue pipe. Here's how it works: When the inducer motor is running, it creates pressure that moves through a small tube connected to the switch. This pressure closes the switch, signaling the furnace's

Never bypass safeties! For educational purposes only. DO NOT TRY AT HOME!! Example of a failed inducer draft motor or bad combustion blower that does not pull (induce) the flame through the heat exchanger. Pressure switch bypasses. Ignition sequence activated and the flame rolls out of the gas furnace. How long does it take before the flame roll out trips? #furnacemaintenance #furnace #gasfurnace #gasheat #hvac #love2hvac #furnaces #hvactech | Ty Branaman

Heat exchanger mode... Pretty cool mode on the @seitronamericas Novo combustion analyzer. Why are we tracking O2? If a heat exchanger has a crack or hole, when the blower fan starts up, it will pressurize the heat exchanger which can be measured in O2. The added pressure is air, that air contains oxygen, so the analyzer is looking for an increase in oxygen. At minimum, a rise of 0.5% can indicate a failed heat exchanger. #combustionanalysis #combustionanalysistools #combustionanalzyer #hvactroub
