Top causes of single-phase motor malfunctions

Most problems with single-phase motors involve the centrifugal switch, thermal switch, or capacitor(s). If the problem is in the centrifugal switch, thermal switch, or capacitor, the motor is usually serviced and repaired. However, if the motor is more than 10 years old and less than 1 HP, the motor is usually replaced. If the motor is less than 1/8 HP, it is almost always replaced.

Fundamental IAQ/HVAC measurements with the Fluke 975 AirMeter™

The 975 gathers ten fundamental IAQ parameters: Temperature, Humidity, Dew Point Temperature, Web Bulb Temperature, Carbon Dioxide, Carbon Monoxide, Air Velocity, Air Volume, and Percentage of Outdoor Air (calculated from temperature or CO2). This application note reviews those parameters and the associated functions on the 975. For more detailed information, see other app notes from the Fluke HVAC/IAQ library.

Insulation resistance and electrical testing for HVAC compressor motors

HVACR mechanics rarely rely on a single test to pass or fail a function or process. As they walk up to a condensing unit, they listen, they wave their hand over the condenser discharge air, and then they grab the suction line, the liquid line, and the discharge line (and wish they hadn't done that). All of this before they even open their tool box.

Why thermal imaging is essential for detecting moisture damage

With the growing concern about mold damage and associated health problems, inspectors are becoming increasingly vigilant in checking for areas of moisture within the confines of the building envelope. Weather related damage and flooding, and subsequent mold growth, have also escalated the need for tools that can facilitate fast and accurate moisture investigations.
