CM Heating performed an electric furnace Diagnostic - Upon investigation, I found that the sequencer has failed which is why all heat elements are not being activated (3 out of 5 work). This is the second replacement sequencer needed in less than 5 years of operation, the unit is an old model of air handler and only source of heat. Replacement of sequencer is needed, however, based on age and efficiency recommend upgrade of system.


Thank you, thank you, thank you for sharing your knowledge. I just replaced our shower cartridge and our leak is FIXED!!!!!!! Your instructional was clear and concise. I did purchase 2 cartridges first, because I did not know the type it was and could not pull it out without the plastic cover it comes with. Fortunately, it was one of the two. By the way I'm a 63 year old woman. If I can do it, anyone with internet and a little patience and an hour can do it.....
High-efficiency condensing furnaces (90% AFUE and above) are a bit more complex than conventional furnaces. The main differences between a conventional and condensing furnace is the heat exchanger technology used to extract heat from the combustion process and the method used to exhaust the combustion gases. In these ways, the furnaces are very different. The condensing furnace does not have a significantly more efficient combustion process than does a conventional furnace; both use gas burners with electronic ignition. The difference lies in that the condensing furnace has a more efficient heat extraction process after combustion.
