White Rodgers # 21D64-2 – Continuity Test (Gas Furnace Ignitor)

Hi, Im Stephany and welcome to restore andReplace, your on-line resource for rapid and easy repairs. At present, had been going to perform a continuitytest for your fuel furnace ignitor. A scorching surface ignitor works in a similar way to anincandescent gentle bulb. As electricity flows via the aspect,the resistance within the fabric generates warmness. This flash of warmness motives the fuel to ignite.The ignitor can burn out over time with normaluse and may just appear singed or cracked. This can be complicated to peer, as even a smallbreak can intent an ignitor to fail. It is first-rate to participate in a continuity scan asthis will verify if a continuous electrical course is reward. Without continuity, the ignitor is not going to operate. All youll want is your hot surface igniterand a digital or analog multimeter. First, disconnect all vigour to your furnaceand isolate or get rid of the ignitor.Be careful when handling the igniters and dont contact the detail along with your fingers. If you happen to use an analog multimeter, set the multimeterto the bottom Ohms of resistance. Next, touch the probes together and adjustthe needle until it can be calibrated at "0". In case you are utilising a digital multimeter, alsoset the dial to the lowest Ohms of resistance. To scan for continuity, take a probe fromthe multimeter and touch it to one of the most terminals. Now, touch the 2nd probe to the remainingterminal. If the igniter has continuity, your multimetershould learn at any place from 30 to 200 Ohms. If there’s no reading on the multimeter orvery little alternate, then there’s no continuity and you’ll haveto change the igniter.In the event you located this video valuable, hit "like".
