- The B13701-54 Goodman Janitrol Furnace Limit Rollout Switch pictured below are found on many Amana, Goodman, Janitrol and other name brand furnaces.
- The B13701-54 Goodman Janitrol Furnace Limit Rollout Switch is used in the following Goodman furnace models:
GMP, GMPE, GMPH, GMP (50Hz), GPD, GMPN, GSMS, GSM (All), PGB024050-1 thru PGB060150-4, PGJ024050-1 thru PGB048100-1. We have a more comprehensive list of furnaces this rollout switch is used on below.
- These rollout limit switches are usually located in several places around the outside of the furnace burner box.
- FYI: The purpose of the limit rollout switch is to stop the furnace from operating in an unsafe condition. When excessive heat (350 degrees or more) is sensed by the limit rollout switch, the rollout switch breaks the circuit in your furnace so your furnace will not operate. These rollout limits prevent a fire or unsafe condition in your furnace.
- You can manually reset the rollout switch by pressing down the pink button that is located in the center of the switch.
- If your limit rollout switch trips it is a good idea to have your furnace inspected by a qualified Heating & Air Conditioning technician. You probably either have a stopped up flue, heat exchanger or a leaking heat exchanger.
- Any of these conditions present a health hazard (possible carbon monoxide poisoning condition or fire) and this should be taken care of immediately. I would strongly suggest that you turn your furnace off until a service technician can look at your furnace. Never by-pass or wire around a limit rollout switch. Several of you have asked me to have these listed on our site. I have accidentally broken a few of these taking the wires off while cleaning furnaces, so I decided to list them on our site.
