Bard part number 8402-156 is an OEM limit control line bracket used to secure and route the limit control wiring in Bard wall-mounted HVAC equipment, helping keep the safety circuit wiring properly supported and positioned during operation and service. A damaged or missing bracket can allow wires to rub, vibrate, or pull loose, which can lead to intermittent limit trips or nuisance shutdowns, so replacing it with the correct Bard OEM bracket helps restore the factory wire routing and reduces the chance of electrical faults. Match this 8402-156 bracket to your unit model and serial number, and verify mounting location during installation to ensure the limit control line is supported exactly as intended.
