It is a sequencer for a furnace, it kicks the fan and dual elements on one at a time.mine started popping and cracking and then only one element would come on,furnace ran all the time because it wasn't getting hot enough.I installed this part which arrived a lot quicker than I thought it would thru US mail.good company,got my order right out without waiting a day like some companies.I would buy from pex supply again also,good people.they also had a very good price,local people around here tried to charge me three or four times more,so do your research people stop making your local shops rich,we have internet now with more competion better people better prices,better service.find out your part number and order online,stop getting ripped off.
