I have a Coleman Evcon Presidential furnace. The pilot light is light but it isn't getting any power to it to actually heat up and fully ignite. I have read where it could be a defective high limit control. Is this a possibility and if so, what is it, where is it located, is it something that I can do myself or does a technician need to come replace it?

Thanks for any information.

Best to have a repair person come and properly adjust this as he would have the proper pressure and leak testing equipment with him and if it needs a replacement part he would either have the part with him or know where to buy it.
