Question about Heating & Cooling
Vanguard wall heater stays lit for 30 mins to a couple of hours and then goes out hvac came out serviced it an it ran great for approximately 6 hours and is now doing exactly as I stated regarding the initial problem prior to calling hvac company, it's Thanksgiving Day and I couldn't get any hvac company out yesterday just found fixya I'm in Oklahoma thank you for any suggestions
Is there a thermostat fitted? If so make sure this is set high enough for the appliance to work. Very simple solution but my mum had a plumber come out to her whole heating system not working all because the thermostat was set too low.

SOURCE: 3.5 TON GSH14 GOODMAN WITH TXV
If it cuts out on heating cycle only, it has to be the metering device at the outside unit, which i think is a txv for that model. Take the outside unit apart, run it in heat and watch the txv and see how it responds, also check the bulb n make sure its secure....

SOURCE: Pilot light won't stay lit
Look for dust and lint. Look for them in places where gas should be freely flowing. I had a similar problem with an Empire Corcho wall-mounted propane ceramic catalyst heater. First it was the pilot light, then the #2 ceramic mantle. After horsing around with the gas lines and pressure regulators and trying to re-aim the pilot, it all turned out to be dust and lint in the gas passages. A little dust bunny in the brass pilot tube gave me a pilot light the shape and color of a banana. One puff of compressed air, and I got back my razor-sharp pilot. And some dust in the chimney of the #2 burner kept it burning blue/yellow and blistering paint off the upper surfaces of the heater. A bit of cleaning with a shop-vac put that right. "Passive" heaters are very much prone to this sort of problem because they rely on convection currents (i.e. LOW velocity) to get the job done. Convection currents are notorious dust collectors, as in COBWEB CITY.

sounds like its not venting properly...it likely is shutting off on a "Spill switch" or "Vent safety switch"....check the vent/chimney first off.....also the pilot could be dirty..,..a lazy pilot tends to blow out easily....pilot should be blue and sharp,,,big enough to fully envelope the thermocouple

Testimonial: "I checked the pilot light and it's clean. I will have to check the chimney next week but thanks!"
