What are some common issues with rooftop HVAC units?
—Common issues include voltage problems, loose blower wheels, and gas pressure issues.
How do you troubleshoot voltage and wiring issues?
—I check for open or closed switches and examine the manual reset options. I also verify the presence and functionality of the inducer.
What can cause a loose blower wheel and how do you fix it?
—A loose blower wheel can be caused by fabric obstruction or improper installation. I tighten the blower wheel to eliminate the problem.
How do you troubleshoot gas valves and gas pressure issues?
—I inspect the gas valve connections and replace faulty valves if necessary. I also check for gas pressure problems that can affect multiple units.
What are some strategies for troubleshooting intermittent furnace problems?
—Intermittent furnace problems can be challenging to diagnose. I recommend checking the thermocouple pilot assembly, gas valves, and electrical connections.
