Troubleshooting Poor Heater Performance
Although a heater may be a simple system, poor performance can be difficult to diagnose, according to Red Dot. Here are two troubleshooting tips that Red Dot says will help with the diagnostic process.

Use a multimeter to make sure full voltage is getting to the motor. If the voltage is adequate, look for worn brushes, dirty squirrel-cage fans, damaged fan blades and other motor problems.
