I have an older aquastar 125 (pilot gets lit with a match);

i have an older aquastar 125 (pilot gets lit with a match); it worked flawlessly for 13 years, then i started having pilot light problems. got some temporary fix by cleaning the pilot circuit, anothe round of burnouts, then disconnected all the thermocouple connectors and brightened them and re-tightened, etc. could always get it to work, but it would blow out after a few days. gave up and went back to tank unit.now a couple years later, am trying again. checked gas filter in pilot tube, got the burner to worker properly for several days, then i blows out again.any ideas>i don't think my unit has the flue tem sensorthanksjm

My hot water heater pilot light will not stay lit. I've gone

My hot water heater pilot light will not stay lit. I've gone through the steps listed on the label to relight it several times and it will not stay lit when I release the pilot knob even after 90-120 seconds. It went out during the night, I was successful in relighting it once and was able to heat the water and then the pilot went out again. What should I check/do next?

I have a White Rodgers 50A50-241 furnace, which is not working.

I have a White Rodgers 50A50-241 furnace, which is not working. Hoping you can help! When the thermostat calls for heat, the blower turns on, the thermocouple glows bright, I hear a click and the burners ignite, then shut off after about three seconds. This cycle repeats itself every ten seconds or so. Any ideas? Thanks for your help!

My furnace fan cycle on off 5 times, runs few seconds

My furnace fan cycle on off 5 times, runs for a few seconds then stops.My furnace fan cycle on off 5 times, runs for a few seconds then stops. I don't hear clicking for it to try to ignite the gas. The gas is not burning. Just the fan part of the furnace is trying to turn on but does not stay on.In the past I had an issue with the gas lighting, and the fan shutting off but it was because the thermocouple went bad. The blinkly light on the furnace blinked irregularly to tell me this. This time around the light blinks evenly which I think is a good sign. The thermostat does not say its trying to heat the house. Thermostat does not tell me when its trying to run just the fan sadly.I have a Nest Gen 2 thermostat that has been installed for ~2 years and no problem until now. The screen turns red when it is requesting heat that it is not red when this problem happens. My question is this normal or is something wrong? I do not know how long it has been happening as I just noticed this.

I have a Jotul fireplace insert operating with a thermostat

I have a Jotul fireplace insert operating with a thermostat at a mountain house in NC. It is closed up for the winter. When I arrived back at the house yesterday the fireplace and pilot were off. I managed to get the pilot back but cannot get the main gas element to go on. I have tried directly touching the two thermostat wires together thinking that it was the thermostat but got no response. The pilot light will not heat the whole house-Help
