Use a flashlight to inspect the interior of the burner assembly. Alibaba.com offers 4,670 testing a gas valve products. The tags shall also be durable and heat-resistant with a brass grommet. How it works: Thermoelectric gas valve is controlled by … There should not be a flame-up there if the valve is working correctly. The furnace has an Intermittent Pilot Ignition System. put one of the leads on MV (main valve ) and the other on MV/PV this is your common terminal. We got it running about 10 times and it lasts anywhere from 1 hour to 24 then quits again. "If you can't explain it simply, you don't understand it well enough". It allows gas testing with helium or nitrogen, to 1.1 times a valve’s maximum specified working pressure (to 1,500 bar, or 22,500 psi). I don't know if your problem was ever resolved n i realize it's two years later but i couldn't resist cuz i just went through very similar situation yesterday. Keep a 1/4 x 1/8 bushing with the manometer to test gas pressure. If your pressure switch didn't close/ pull in, the ignitor would never glow, it wouldn't get to that point. Our Control Valve Test Rigs are available in both horizontal and vertical configurations with the option of 90° rotation. I was wondering if you could tell me what your problem ended up being and what you had to relplace or repair. How do I test the gas valve to see if the Main Valve is getting voltage? If you can't light the pilot, the problem most likely lies with the gas control valve or the gas flow itself, not the thermocouple. Hey so I have the exact same problem right now and it's 40 degrees, no heat on a Sunday evening. SSBCEPL provides Nitrogen gas-free services, gassing up and cool down services for refrigerated Propane, refrigerated Ethylene and Propylene. Testing EGR Valve Diaphragm Condition. On 2017-08-25 by (mod) - start by turning the gas valve off between the meter and the building. It was a gas pressure problem. Mark, if indeed 24v at valve, and no gas flow, tapping is also a great recommendation. Put in a 1/4" brass plug. • LPG gas cylinder testing normally includes the replacement of the main valve when gas bottle testing takes place, for re-certification, when gas … If you have ever had the Allen wrench strip out an aluminum plug it is a PIA. That allows the main valve inside the gas valve to feed the main burners with gas. All tags shall be CGA color-coded and gas-specific. Sweep out any hair, lint and foreign debris with a feather duster. Locate the gas valve -- it's usually behind a grill on the front of the fireplace -- and find the copper thermocouple wire leading from it. Have an assistant plug in the appliance and turn on the gas feed valve. As soon as I get home from work, I will try this and let you know if it works. A normal reading will be in the range of 145 to 195 millivolts. For a better experience, please enable JavaScript in your browser before proceeding. Generally, I know how to use a voltage meter. If the reading is higher,magnet is defective therefore Change the Valve - … If you read 24 vac then your valve is bad.....if you read anything other then 24 vac (less) then the control is not telling the valve to open and yes it may be the flame sensor. The gas furnace is a Tempstar 5000 (model: NUGE075BG01). Readings outside this range indicate the gas valve is defective and must be replaced. Dryer won’t heat? Gas valve; Diverter valve; Circuit board; Should the internal resistance measure infinity/no resistance when the component is disconnected, then the faulty component has been traced. This supply is governed by a vacuum switch which in turn is activated by a signal from the Electronic Control Module (ECM). Valve leakage is tested using either a hydrostatic test (i.e., the test medium is a liquid, such as water or kerosene) or a pneumatic test (the test medium is a gas, such as air or nitrogen). Please help me as soon as you can. For a vacuum system, helium is “sprayed” near the likely leak locations. HVAC repair is not Rocket science.........Guess thats why i don't work for NASA :laughing: I have the exact same issue, did you figure out what the problem was. The furnace will be turned on next. Be sure when checking that you are checking the voltage directly across the gas valve itself. The gas pilot valve is the piece that supplies fire to the gas. A wide variety of testing a gas valve options are available to you, such as material, structure, and media. With NFPA-99 and CSA standards and how you check for gas cylinder leakage valve: gas.
