Works really great -- very happy. I doubt I'll ever need one again, but if I did, I'd buy it again in a heartbeat. Honeywell S8610U3009 Furnace Intermittent Pilot Control lights up on my system almost immediately. Some heating systems have, and can, have programmed delays. Inexpensive it looks like it can work with almost any oven so check before ordering they sure have a long list of compatible controls it can replace. I am just a homeowner and am not affiliated with this product in any way. That's how I came to buy it. My 37 year old Carrier air conditioner/heater combination with original intermittent pilot control has failed, no spark. Our oven doesn't get used as much as some people do and I'm pretty sure new appliances these days aren't going to last as long, at least not my neighbors. It is this part of Pilot Control that is currently out of production. Carrier had a chance to catch their breath with a new $400 Carrier LH33CM600 spare that was in stock at the time. A little desperate and not knowing as much about Honeywell Control as I do now, I found a new Carrier LH33CM600 from memory on e-bay for about $165. It was old stock but you could see it was never installed. The UT Electronic Controls Carrier unit never worked very well and I was never able to contact the UT manufacturer. The good news is that he lit the stove but struggled a bit. I was able to contact Carrier tech support, they spoke to me but there was no answer to my technical questions, installation questions, nor did they have any suggestions. Carrier's new control system worked during the coldest part of this winter and then failed. My Installation Notes I'm not an expert, surely your situation will be different, please consult an expert first. The installation is somewhat technical, especially for me on the part of the carrier I installed first. Read all Honeywell instructions first. I would suggest taking a good, clear digital photo of your old equipment's wiring before you begin. First, search your oven or the internet for a wiring diagram, which may also help determine wiring functions. The high voltage ignition wire on my particular stove was close to shorting on my two replacements, but it worked with a little fuss. In my case I also added a ground wire from the pilot's mounting frame to the "GND" terminal to ensure a good ground path for flame straightening - you may already have it, or of course you may have another. In my system, this is how the "SENCE" terminal detects the flame orientation on the pilot flame when a flame is present. Again, this is what I did on my system, no suggestions on how to do your system. In any case, remember to turn off/disconnect all power before working on your system.
