electric furnace sequencers

I have a blower that stays on for awhile. decided it is the sequencer. I could hit it and will shot off. If one is bad should I just replace them all. it is a 5 switch sequencer. 24a34-14 white rogers I tripped the breaker a couple of times in the garage, about a month ago. figured that was unrelated.

Sequencers are designed to bring on one strip at a time so as to not pop the breaker, to not over amp the circuit. If that happened than I'd change them all.

electric furnace sequencers

After running my Furnace for a while. 20-30min. The blower/fan will stay on at the low speed. It will run on low for about 30min to an hour. I would give it a hit and it would shut off. (would hear switches closing/opening as well). I believe it is the blower motor relay. It is an old furnace but found a replacement part. However, to save money, can these swtiches be taken out and cleaned? Should I slide the lever Down to 80-85 or up to 95? (it is a sliding lever). Here is the old part #F214-14A9-140-25C. I have another switch. that I think does the high speed blower part#F47TS2-7T-110C , (this number was the best I could read it). Thoughts?
