Have HVAC Questions? Ask an HVAC Expert for Answers
Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation
I assume you mean a GKS not a CKS. Is the draft fan running?
Ok, is the draft fan (the small fan on the front of the unit) running?
Ok, is the thermostat set to heat mode? if it is then we'll have to do a little trouble shooting to figure out what's going on. The first thing to try is to connect the leads on R & W on the stat together. Best to turn the power off first then turn the power back on once you have those leads jumped.
Ok next go to the terminal strip on the furnace and jump the R & W terminals. Be sure you put the blower door panel back securely in place. The unit won't run if the panel switch is not engaged (pushed all the way in).
I'm going to open this backup to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
Please attach a well focused, close up photo of the wiring diagram glued inside the service panel, you can use the paper clip-icon at the right end of the toolbar at the top of this dialog box, Include a picture of the thermostat wire connections to the printed circuit board in the same area.
If there is no paper clip-icon, look for the '+attach files' link at left of your send button.
I can mark it up with trouble shooting instructions. You will need a multi meter ($30 at a hardware store) and some experience working with appliances, let me know a lot about your skill sets in those regards.
If none of this in your skill sets, tell me which direction you are from the center of the nearest city and I will look for a few well rated service outfits in your area.
We can go from there.
