hey all,
boy does this hit home....this has happened to my FEC 500 4 times!....kept having to replace the relay [its the top little black square relay] also I have had to replace the large relay/converter [3 times]. the one that has a green light on...very frustrating! and costly,[both the cost of parts and loss of smoker time]. after the fourth time, me and my son-n-law Kelly[who has an engineering degree] figured out why we were having continuous problems. we have our smoker mounted on a trailer. so we did a water test, going up from the power converter[with green light] it goes through the upper wall of the unit. its all[wires] in PVC pipe. we poured water onto the connection and guess what??? water was coming down onto the converter shorting it out. evidently over time the seal at that joint[pvc pipe] leaks. so we caulked every PVC pipe joint, replaced the electrical components , and now there are no more problems.......I think cookshack should pass on this info. to all who have FEC'S,300,500,750's. plus all components can be replaced by buying them from on line elec. part sites....so now we keep back up parts so if there is a prob. we will have no down time.......belts too...hope this helps......
