How To Test Hot Surface Ignitor
Testing a hot surface ignitor is a relatively simple process that can be performed with a multimeter. By checking for continuity between the ignitor’s terminals and testing for proper resistance, it is possible to determine whether or not the ignitor is functioning correctly.
How To Test Hot Surface Ignitor
There are a few ways to test a hot surface ignitor. One method is to use a multimeter to measure the resistance across the ignitor. Another method is to use a continuity tester to check if there is a continuous electrical path through the ignitor.
Tools: -Phillips head screwdriver -Needle nose pliers -Volt/ohm meter -Torque wrench Material: -Hot surface ignitor
- check that the power is off to the furnace and the furnace switch is in the “off” position. 2. remove the front access panel of the furnace. 3. locate the hot surface ignitor. 4
below -Check that voltage is present at the ignitor terminals. -Check that the ignitor is receiving power by checking for continuity between the ignitor and the flame sensor. -Check that the ignitor is sparking by holding a piece of metal against the ignitor electrodes.
Frequently Asked Questions
How Do You Know If Your Ignitor Is Bad?
The ignitor is responsible for igniting the fuel in the furnace, so if it is not working properly, then the furnace will not be able to heat your home. There are a few ways to test if your ignitor is bad. One way is to check the resistance of the ignitor. If it is not within the manufacturer’s specifications, then it may be bad. Another way to test the ignitor is to see if it is getting hot. If it is not getting hot, then it may be bad.
How Do You Check A Spark Igniter?
The spark igniter is checked by looking at the arc that is created when the igniter is sparked. The arc should be blue and consistent.
How Many Ohms Should A Hot Surface Ignitor Have?
A hot surface ignitor should have a resistance of 10 to 30 ohms.
To Summarize
Testing a hot surface ignitor is a relatively easy process. The ignitor can be tested with a multimeter to ensure that it is functioning properly. If the ignitor is not working, it will need to be replaced.
