Furnaces may have multiple limit switches. Limit switches are found on all types of furnaces, whether they run on oil, gas or electricity.

The limit switch also controls when ...

If air flow is restricted the heat is not dissipated quickly enough, and the high limit switch will kick in as the furnace overheats. Make sure the filter is clean, and the appropriate density for your furnace. If a different filter does not fix the issue, it may be caused by an under powered blower motor. – The furnace will start up in either intermediate-, or maximum-heat. The furnace will transition and operate at minimum-heat or the calculated modulating rate after starting and operating for 45 seconds at intermediate-heat. The furnace control CPU defaults to minimum-heat on the first thermostat cycle and calculates the modulating rate a heat cycle, both furnaces terminate the call for heat immediately. The only chance for blower mis-synchronization is if the blower off delays are set differently on the twins. If a twin fault occurs during high speed fan or continuous fan, both controls shut blowers off immediately. 6 flashes Limit Switch tripped 5 times during heat cycleIn this episode of Repair and Replace, Vance shows how to replace the high limit switch in a gas furnace.
