Locate the Inducer Motor
Inducer motors are important for sucking out fumes from gas furnaces and boilers. Here’s how to locate it like a pro.
- Remove the furnace panels to expose the interior. Inspect the venting system and follow it back to the furnace. You’ll find the fan motor near the end of the vent pipe.
- Look for a white PVC or black metal pipe coming out of the roof or wall. This is the flue pipe and can help you find the inducer motor.
- Check around and below the control board inside the furnace’s access panel. The inducer motor should be attached to wires.
If you can’t find it, consult your owner’s manual or contact an expert. Remember, not all furnaces have an inducer motor. Its position and style may vary.
Old gas furnaces had gravity-fed exhausts relying on natural ventilation. But due to safety concerns, manufacturers included mechanical devices, like draft fans, leading to today’s inducer motors. Finding physical damage is hard – but at least with your furnace, you won’t get poked!
Check for physical damage
Inspecting the inducer motor is essential for running the HVAC system. Part of this process is checking for physical damage. Here are some steps to follow:
Safety measures must be prioritized – don’t touch exposed electrical components.
A technician failed to detect physical damage in an aged HVAC inducer assembly. This caused excessive vibration and further internal damage within two months. Inspect and maintain your HVAC Inducer regularly to prevent this. Lastly, check for voltage to ensure your motor is the only thing sparking.
Test for voltage
Testing voltage is key when examining an inducer motor. A multimeter is an ideal tool to measure the voltage at connections and components. It’s a handheld device that reads electrical currents, helping you spot any issues with the inducer motor’s performance.
To carry out a successful voltage test, make a table with columns such as ‘Connections‘, ‘Voltage‘, and ‘Acceptable range‘. Test each connection in each component separately and see if it is within the acceptable range. For instance, when testing connections between GND & VCC, put probes on each connection; black on GND (Ground) and red on VCC (Voltage). Pay attention to the polarity; if not followed correctly it will result in incorrect readings.
Besides testing voltage continuity with a multimeter, you can also look for voltage drops across circuits or wires. A high voltage drop shows resistance, meaning the inducer motor needs more current which leads to it deteriorating over time.
An industrial electrician faced costly downtime due to issues with his inducer motor. To diagnose the problem, he used different meters like an ammeter and voltmeter to test all components. He found zero resistance across one of the components, which ended up needing to be replaced.
Checking the pressure switch is like viewing your blind date’s profile prior to the first date – it’s essential to make sure everything is in order.
Check the pressure switch
When troubleshooting an inducer motor, check the pressure switch. This ensures the motor is functioning. Disconnect the power source first. Locate the pressure switch near the draft inducer motor assembly. Gently remove the tubing or hoses. Test for continuity with a multimeter. No continuity? Replace the switch. Resolve other issues first. They can affect the results.
A study by Modernize showed average homeowners spend $200-$400/year on HVAC repairs. A bad capacitor isn’t someone obsessed with working out.
Check for a bad capacitor
A capacitor is a vital part of an inducer motor. It stores and releases electrical energy when needed. If the capacitor is bad, it can lead to a faulty inducer motor which causes heating or cooling issues. To keep the motor running, you need to check if the capacitor is bad. Here’s a guide:
- First, turn off the power supply to the inducer motor.
- Locate the capacitor which can be inside the blower compartment or another part of the furnace.
