Carrier LA22LA138 Blower Wheel 321894-706 providing the specific resistance-to-temperature curve

providing the specific resistance-to-temperature curve necessary for accurate data acquisition without the signal drift common in universal alternatives

If the inducer motor fails to pull at least this much pressure

Using a switch with a different limit switch temperature range can lead to heat exchanger damage or unsafe operating conditions

it generates its own operating voltage via the pilot flame heating the thermopile/generator

Reduced System Downtime: Resolves common ignition failure lockouts caused by corroded or fouled sensing rods
