Learn to diagnose, troubleshoot, and repair common forced air furnace issues through step-by-step tutorials and expert tips. Save money by performing DIY repairs and understanding furnace components.
Learn to use essential furnace diagnostic tools—multimeters, manometers, gas and carbon monoxide detectors, and hand tools—to accurately diagnose limit switches, motors, flame sensors, and gas leaks.
Explore basic electricity in furnace repair, defining voltage, amperage, and resistance, and reading these on components, switches, and transformers. Follow safety practices, ensuring power is off before readings.
Explore the sequence of operation in a residential furnace by identifying core components like the inducer, pressure switch, igniter, flame sensor, heat exchanger, and blower, coordinated by the control board.
Troubleshoot residential thermostats by checking furnace 24v power, wiring from r to w, g, y, and common, and testing with voltage and continuity.
Learn to troubleshoot inducer motor issues by testing thermostat voltage to the W circuit, verifying 120V at the inducer, and distinguishing a bad control board from a faulty motor.
Test the pressure switch as a safety device, ensuring it closes with adequate vacuum from the inducer. Measure inches of water column with a manometer (0.41 in H2O).
Diagnose igniters by unplugging and testing resistance across its two wires, noting values like 16Ω, 80Ω, or 4.5Ω, then verify ignition by checking voltage and inducer and pressure switch operation.
Diagnose flame sensor issues in residential furnaces by testing microamp readings and diagnostic codes, then clean or replace a carbon-buildup sensor to ensure reliable flame sensing.
Troubleshoot a residential gas valve by verifying 24V control, diagnosing pressure switch signals, checking incoming and outgoing gas pressures, adjusting outlet pressure, and performing leak checks.
