  ❶ Understand What a Run Capacitor Does The run capacitor provides continuous phase-shifted current to the motor start winding, allowing the motor to run: With the design efficiency In the right direction With the appropriate torque With near “unity” power factor (power factor near 1.0) If the run capacitor is failed, the motor often […]

Proving flame is an important part of the gas firing sequence. Without proof of flame, you risk dumping unspent gas into the heat exchanger, resulting in an explosion. There are many ways to “prove flame,” but we are focusing on the flame sensing rod (flame rectification) method here. Here are the facts: Flame sensing rods, […]
