Hello,
We have a whirlpool gas range (from 1999) with sealed burners and have
had this problem for several months in which 2 of the burners
don't light up when the knob is turned on.

We do hear the clicking sound and the burners light up w/ matches.

We have the electric igniters.

Is there a way to know if the problem is the igniter or something
inside is dirty?

The gas much reach the spark to ignite. Check that there is no gunk built
up where the gas would flow to the sparking igniter. In some cases, one
sparking igniter will take care of two burners. Go take a peek underneath.
