High Voltage An 80-volt HSI should have about 80 volts applied to it. Applying 120 volts to that HSI will cause it break, and sometimes almost immediately. Having too low of voltage may not let the igniter burn hot enough.

Why is my furnace igniter not working?
If your furnace won't ignite, the source of the issue may be a broken flame sensor. The sensor is responsible for turning off the gas burners to avoid gas buildup. Once this component starts to malfunction, it may stop the burners from igniting altogether.

Failed Hot Surface Ignitor Diagnosis
What causes an igniter to fail?
As mentioned above, sometimes the cause of a furnace ignitor failing to ignite is due to a safety issue, such as a clogged air filter, for instance. Air filters should be changed on a regular basis, to prevent these kinds of problems. However, a lot of furnace owners fail to do this.

Checking A Hot Surface Ignitor
What causes a ignitor to fail?
Faulty ignitors may be caused by a high-voltage supply of electricity, which may cause short-circuiting. Having a worn-out ignitor may also impair the furnace's performance, so it's important to replace it after several years of use.
