The thermocouple is a copper rod that the pilot flame heats-up. When it gets hot enough, the thermocouple signals that there is enough heat to burn the gas fuel being released into the appliance—and so it allows the gas to be released to the burners. In some cases where the pilot light won’t stay lit, the thermocouple needs to be adjusted or replaced. This is generally a job for a professional.
Zach came early, which I very much appreciated, and got the job done quickly. He was unfailingly polite and took care with putting on the booties and keeping my carpet clean. He managed to get the sprinkler system turned off even though I was quite uninformed about it and could help very little beyond pointing to where things were. I am always happy to have Brothers people come out to do my plumbing, heating, & electric services.

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.

The flame sensor safeguards your furnace against the unsafe burning of fuel, and a dirty flame sensor may cause your furnace to function improperly. Typically, the flame sensor comes in the form of a rod that can be found near the back of the furnace, right in the path of the burner. To clean the sensor, turn off power to the furnace at the breaker box. Then, if possible, remove the sensor from the furnace. Scrub the sensor gently to remove dust and other residues. Finally, reattach the sensor and resume power to the furnace.
My furnace thermostat stopped working, and when I called Dehlia answered the phone and set up an appointment. They charged less for a diagnostic call than larger companies. They are actively licensed, bonded and insured. Verne arrived 2 days later, explained what was broken in my 17 year old furnace and gave me an estimate and time of replacement for a new furnace. Dehlia confirmed via email and phone, and Don and Zack showed up as promised on time a week later and replaced my Bryant 90i furnace with a new Rheem 96% efficient 2 stage Variable speed 85,000btu gas furnace Model #R96VA0852521 and provided me with the paperwork warranty and removed the old one. Cost was $5,394.90 including tax. I gave up on trying to get 2 more estimates because every furnace company wants $125 to $200 to come out to do a diagnostic and this company wanted $75 to come out to look at it although admittedly they just took a look at it and said it was broken and repair would be $2 to $3k and should just get a new  one (this fee was waived when I agreed to buy a new furnace from them). They also said it was possible I could find cheaper installation elsewhere, but I was freezing in December and I just wanted heat and other companies were 2 to 3 weeks out for an appointment.  They were pleasant to chat with as they worked and Don updated a convoluted furnace exhaust piping system. They accept cash and check after a job is finished with no deposit up front and are clear that 3% is added if you pay via credit card.  Overall I am happy with my new furnace although I sure wish I could've replaced it myself to save some money.
Keeping too many heat registers closed can cause heat to build up in your furnace, forcing air out of duct leaks and requiring the blowers to compensate for the added pressure. Essentially, blocking heating vents causes your furnace to work harder and longer than it is intended to work. Further, it forces air pressure to build up in your air ducts, which may both cause and worsens airflow leaks — particularly at joints and seams. Pros recommend keeping at least 80 percent of your heating registers open to prevent unnecessary air from building up in your furnace.

Cut down on energy costs and prevent damage to your furnace by addressing a gas furnace that's overactive or short cycling. Besides the need for consistently comfortable temperatures, this issue could cause long-term safety issues to your home, making it very important to address. From a faulty thermostat to a dirty filter, there are several possible causes to investigate.
