8402-172 OBSOLETE
- Limit Control L165-7.0
Bard part number 8402-172 is an OEM limit control (L165-7.0) used in Bard heating sections to monitor discharge or cabinet temperature and help protect the furnace from overheating by opening the safety circuit if the temperature rises beyond its setpoint, then returning the unit to normal operation once conditions are safe. This replacement control is intended to match Bard factory fit and wiring in applicable wall mounted gas electric equipment, making it a practical fix for nuisance limit trips, no heat complaints, or a failed safety switch when diagnosis confirms the limit is the cause. Confirm compatibility by matching the exact part number 8402-172 to your unit model and serial information and replace using standard electrical safety procedures.
