Reliable Actuation: Maintains consistent pull-in and holding voltage to prevent contactor buzzing or intermittent system operation
any structural failure here often leads to pressure switch trips or water damage to the furnace deck
it utilizes a 1-3/8" x 2-1/4" coiled sensing bulb to ensure high sensitivity and accurate thermal response
By integrating a high-performance hot surface ignitor alongside the central logic controller
and discharge gas lines with a minimum pressure differential requirement of only 1 psi for full operation
