Yes, you can replace a glass cooktop, and it's often cheaper than replacing the whole range
A cracked or damaged glass cooktop does not mean you need a new stove. Most glass cooktops are removable parts that you can order as replacements and install yourself or have a technician install. The cost of a replacement cooktop is typically one-third to one-half the price of a new range, and the job usually takes between one and three hours depending on your stove model and whether you do it yourself.
The catch is that you need the exact model number of your range to order the right cooktop. Glass cooktops are not universal — a cooktop for a GE range will not fit a Whirlpool, and even within the same brand, different model years use different glass. Once you have the correct part, the actual replacement involves disconnecting electrical or gas connections, unbolting the old cooktop, and securing the new one in place.
Key Takeaways
- Find your range's model number on a sticker inside the oven door or on the back of the unit, then order the exact replacement cooktop from the manufacturer or an appliance parts retailer.
- Glass cooktop replacement costs between $200 and $600 for the part alone, depending on the brand and whether your range uses electric coil burners or a smooth glass surface.
- The job requires disconnecting power (for electric ranges) or the gas line (for gas ranges), so if you are not comfortable with those steps, hire a technician instead of attempting it yourself.
- Most ranges have the cooktop bolted down from underneath, which means you will need access to the space below the stovetop to complete the replacement.
- Installation typically takes one to three hours, and you should test all burners and the oven before considering the job complete.
Finding the right replacement cooktop for your range
The model number is the key to ordering the correct part. Open your oven door and look for a sticker on the inside wall — it usually lists the brand, model number, and serial number. If you do not see it there, check the back of the range or the side wall inside the oven. Write down the full model number exactly as it appears.
Once you have the model number, contact the manufacturer directly or search for the part on appliance parts websites like AppliancePartsPros, PartSelect, or Sears Parts. You can also call the manufacturer's customer service line and give them the model number — they will tell you the exact cooktop part number and the current price. Prices vary widely depending on the brand: a replacement cooktop for a basic electric range might cost $250, while a high-end gas range cooktop could run $500 or more.
Before you order, confirm that the cooktop is actually replaceable on your model. Most modern ranges have removable cooktops, but some older or lower-end models have the glass fused permanently to the frame. The parts retailer or manufacturer can tell you whether your range supports a replacement.
What you need to do before starting the replacement
Turn off the power to your range at the circuit breaker if it is electric, or turn off the gas supply at the valve behind the stove if it is gas-powered. For electric ranges, you can also unplug the unit if it has a plug. Wait at least 30 minutes for the cooktop to cool completely — even if you have not used it recently, the glass can retain heat.
Clear the area around and below the stove. You will need access to the underside of the cooktop to unbolt it, so if your range is built into cabinetry, you may need to remove drawers or panels underneath. Lay down a towel or drop cloth to protect your floor and to catch any small parts that fall.
Gather your tools: a socket wrench or adjustable wrench (size depends on your range, usually 1/4 inch or 3/8 inch), a screwdriver (Phillips and flathead), and a helper if possible. The cooktop is heavy and awkward to handle alone, and having someone steady it while you work underneath makes the job much safer.
Removing the old cooktop step by step
For electric ranges, locate the electrical connectors underneath the cooktop — they are usually push-on terminals or screw-down connectors. Take a photo of how they are connected before you disconnect them, so you know how to reconnect the new cooktop. Gently pull the connectors apart or loosen the screws. If the connectors are stuck, wiggle them gently side to side rather than pulling straight out.
For gas ranges, you will need to disconnect the gas line. This is the step where many people call a technician instead of doing it themselves, because a mistake can create a gas leak. If you are comfortable with it, locate the flexible gas line connected to the cooktop, turn the shutoff valve clockwise until it stops, and then use a wrench to loosen the fitting where the line connects to the cooktop. Have a rag ready to catch any residual gas. If you are not confident, stop here and call a professional.
Once electrical or gas is disconnected, look underneath the cooktop for bolts holding it to the frame — usually four to six bolts around the perimeter. Use your wrench to remove each bolt, working from one side to the other rather than removing them all from one spot first. This keeps the cooktop balanced as you work. As you remove the last bolt, have your helper support the cooktop from above so it does not fall.
Carefully lift the old cooktop away from the frame and set it aside. You may need to angle it slightly to clear any remaining connectors or brackets. Clean the frame where the old cooktop sat — use a damp cloth to remove any debris, dust, or old gasket material.
Installing the new cooktop
Position the new cooktop over the frame and lower it into place. It should sit flush with the surrounding countertop. If it does not sit evenly, check underneath for debris or misaligned brackets and adjust as needed.
Insert the bolts through the frame holes and into the cooktop, then tighten them in a crisscross pattern — tighten one bolt partway, then move to the opposite side and tighten that one partway, and so on. This ensures even pressure and prevents the cooktop from warping. Once all bolts are snug, do a final tightening pass to make sure they are find but not over-tightened, which can crack the glass.
Reconnect the electrical connectors or gas line using your photo as a reference. For electrical connections, push the connectors firmly onto the terminals until you hear or feel a click. For gas connections, use your wrench to tighten the fitting — hand-tighten first, then use the wrench for a final quarter-turn. Do not over-tighten gas fittings, as this can damage the threads.
Turn the power back on at the circuit breaker or turn the gas valve back on. Wait a few minutes, then test each burner on the cooktop to make sure it heats properly. For electric ranges, all burners should glow red within 30 seconds. For gas ranges, all burners should ignite and flame should be even across each burner head. If any burner does not work, turn everything off and check your connections.
When to call a professional instead
If you are not comfortable working with electrical connections or gas lines, hire a technician. The cost of a professional installation is usually $150 to $300 on top of the cooktop price, but it is worth it for peace of mind and to avoid the risk of a gas leak or electrical problem.
You should also call a professional if the cooktop does not sit flush after installation, if you cannot locate or remove the bolts, or if the old cooktop appears to be glued or welded to the frame rather than bolted. Some older ranges or certain brands use permanent adhesive instead of bolts, and those cooktops cannot be replaced at home.
Frequently Asked Questions
How long does a replacement cooktop last?
A replacement cooktop should last as long as the original — typically 10 to 15 years depending on use and maintenance. The lifespan depends more on how often you use the burners and how well you clean spills than on whether the cooktop is original or replacement.
Can I replace just the glass if it is cracked but the burners still work?
No. The glass cooktop and the heating elements underneath are one sealed unit. If the glass is cracked, you must replace the entire cooktop. A cracked cooktop is also a safety hazard because moisture can seep into the heating elements and cause electrical problems.
What if I order the wrong cooktop by mistake?
Most appliance parts retailers allow returns within 30 days if the part is unused and in original packaging. Check the return policy before you order. If you have already opened or installed it, you may not be able to return it, so double-check the model number before ordering.
Do I need to replace the gasket or seal when I install a new cooktop?
Most replacement cooktops come with a new gasket or adhesive strip already attached. If yours does not, the parts retailer will tell you what gasket to order separately. Do not reuse the old gasket — it will not seal properly and can allow heat or moisture to escape.
Can I use my range while waiting for the replacement cooktop to arrive?
No. Once the old cooktop is removed, the range is not safe to use. Do not attempt to use the oven or any burners until the new cooktop is fully installed and tested. Plan your replacement for a time when you can be without your stove for at least a few days.
