Carrier Weathermaker 8000 ignitor won't glow...
Hi, If you can take a good light and just look at the glow end of the hot surface ignitor, 95% of the time you will be able to see where the break is on the glow surface. If you have excess to a electrical meter, you would unplug the hot surface ignitor, that is the correct name for it and set the meter for continuity. Touch each lead from meter to each wire and you will show a reading of some kind if it is good, and nothing if it is open or burned out. If you are lighting it by hand (dangerous) it shows that the inducer motor, flame sensor, and main gas valve are in good shape. I know when its cold you have to do what it takes. If the main controller which may be a control circuit board with a red led light on it, or it may be a blue, or gray, white control box with wiring going to it with markings such as TH, TR, C, MGV, PV, Ect. on it and would be right where you are working to light the pilot manually. If it runs when you light it by hand, the control box is good or it would lock out when you would light it. Check out that hot surface ignitor/ glow plug. The part number is imprinted on it. It is either a 120 volt or may be 24 volt hot surface ignitor as some models have one or the other. A tip when installing the new one. Do not touch the surface end that glows with your fingers in anyway, as the oil from your fingers will cause it to burn in half! What happens to these hot surface ignitor is dust settles on them over time and causes them to burn in have or a crack in them. Rheem and Ruud units came out with there's mounted in a horizontal position and they kept burning out fast as dust would build fast. They finally come up with a bracket to mount it in a vertical position and solved this problem. Anyway, unplug it, pull it out and inspect it very good for any signs of a tiny crack or what ever. Ohm it out if you have a meter. You can buy one at a appliance parts house and they are very reasonable. Please keep me posted on what you find. I will be here for help. I wish you the best as I know you can do this.
