Gas cooktop installation guide:
How to install a gas cooktop into a kitchen countertop. This article describes the steps in cooktop installation and includes warnings from the real world of "what can go wrong" and what to do about it.
Page top photo: a Bosch gas cooktop with installation nearly complete; a temporary wood block wedged between cooktop and the wall backsplash is holding the cooktop in precisely-aligned position for final securing and sealing.
This article series explains the steps in installing & testing gas appliances and includes a detailed procedure for converting from LP gas or "bottled gas" to natural gas or "piped in gas" at a building.

Watch out: Most manufacturers require that installation and fuel conversions shall be performed by a trained and qualified service technician and local building regulations may require gas appliance installation by a licensed professional.
The appliance installation technician should be sure to correctly identify the model number of your gas appliance so that s/he can follow the correct details of the manufacturer's instructions.
Shown above: our converted (to LP) Bosch gas cooktop ready for installation into the countertop.
Watch out: If your gas cooktop came from the factory set-up for natural gas and your fuel source is propane (or vice versa) you should complete all of the gas conversion steps before proceeding to install the cooktop into the countertop.
See GAS APPLIANCE CONVERT LP-to-NATURAL GAS if you need to make this changeover.

But before going through the natural gas to LP gas conversion procedure you might want to perform a quick test fit and make necessary measurements to be sure that your cooktop will indeed fit since if you bought a cooktop that cannot fit into your installation location, trying to return it after you've fooled around with converting its components between fuels may make exchange difficult.
Once a gas cooktop has been converted to the proper fuel, the remaining installation steps will involve at least the following steps that we list immediately below and that we illustrate in detail
at GAS COOKTOP INSTALLATION DETAILS
Tools listed by the manufacturer for converting between natural gas and LP gas or propane and for installing a gas cooktop or range will typically include a small-bladed screwdriver, a nut driver, and wrenches.
It's a rare installation job that goes like clockwork without encountering a surprise, as we will illustrate.
For example you may need a hammer and chisel if minor adjustments to wood obstructions intrude into the appliance opening, and you will certainly need both thread sealant designed for gas piping installation and a gas leak detector solution.

Above left are the manufacturer's instructions, slip joint pliers, a marker, a metric hex key set (more on this later), a small bladed screwdriver that fits the burner control knob air adjustment screws (more on this later), and a magnifying glass that let blind old guys read the stampings on the spuds or gas orifices.
Above right is the measuring tape you should have been using to check all measurements before ever ordering your gas cooktop, lest the cook top you ordered not fit into the countertop where it's to reside.
Watch out: when measuring for a cooktop installation into an existing countertop or you may find surprises. Above left are the hammer and chisel we needed to trim a bit of plywood that was a surprise intrusion into the opening into which the cooktop had to fit (more on this later).
Above in our second photo are two adjustable wrenches needed to remove old or install new gas piping connections. Why two wrenches? One has to hold one member of a pair of fittings being screwed together while the second turns the second member tight.
Watch out: if you do not use two wrenches you may twist and damage the short nipple that extends from the bottom of the gas cooktop. You'll be sorry.
And you'll need a nut driver sized to match the spuds or orifices to be removed or installed along with a gas leak detector and thread sealant formulated for use on gas piping
. As the manufacturers all insist that gas appliances should be installed only by a qualified technician (or by a licensed installer as is required by building regulations in some jurisdictions) we know you'll have all of these tools and supplies, but it's nice to have them at hand.
For example, the nut driver for modern gas appliance spuds may be a size that you didn't have, or you may have nut drivers only in inch-dimensions and you may need to buy one in metric dimensions to avoid damaging the brass orifice spud.

First try pushing the knob inwards towards the stove. As a child safety feature, newer stove and cooktop control knobs lock in the "off" position unless pushed in before turning.
If other knobs work properly on your stove but this one does not, I'd turn off power and fuel to the stove, then try removing the knob assembly for a closer inspection. You may need to replace it but sometimes we find spilled food, especially sticky food, has fallen into the mechanism and needs removal, perhaps by soaking in a de-greaser or soap solution overnight.

I have a 1992 sears gas stove. The only problem is the ignitor does not operate, no click sound, when the front burner handle is turned to lite. However, the ignitor does operate when the rear burner handle is turned to light; the familiar click sound is heard. The ignitor is the same one for the right side front and back burners. I looked at the electrical connection and it is not loose or have a signs of a short.

Anon, take a look at the gas stove igniter repair discussion at GAS COOKTOP or STOVE IGNITER REPAIR.
If your unit has power but there is no click and no spark at the igniters I suspect the control module has failed.
