Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Jx3 gas cooktop upgrade

Submitted by j - 8/9/2017

I bought this cook top to convert from electric to gas. easy installation. easy to use. Burners have nice range of btu's and water boils quickly on largest one at 6500ft altitude. Cleaning isn't too bad. The downdraft filter catches crumbs and food and can easily be pulled and run through a faucet to clean. It looks nice in our countertops and definitely adds to the kitchen appearance. Would buy again.

Yes, I recommend this product

like the stainless. also like the simmer burner is on the ba

Submitted by shelia jones - 8/8/2017

as I said I like the stainless. my former jenn-air was a four burner with a center downdraft with a glass base. I can honestly say I hated it. Cleanup was a nightmare. I like the simmer burner is in the back so more frequently used burners are up front and more convenient.I also like the vent is more shallow and easier to clean. I like that the knobs are stainless. my former ones were plastic. tacky

Yes, I recommend this product

Great Stove!

Submitted by Sandy - 7/13/2017

This stove is great! I love that the knobs are stainless and are on the side of the stove. Our last stove had plastic knobs in the middle and we were forever melting them. It's easy to clean, attractive, and cooks great!

I wish the would redesign the downdraft

Submitted by T - 5/19/2017

I like the look of a island cooktop. Need a better downdraft vent.

No, I do not recommend this product

Looks good and works fine

Submitted by David - 5/11/2017

Slick design with even heating and precise controls. The downside is the downdraft. There doesn't seem to be any difference in fan speed, amount of air moved or noise between the high, medium and low. All three are noisy. I would recommend this cook top to the casual cook with the noise warning.

Yes, I recommend this product

Great cooktop! Definitely Recommend!

Submitted by Michelle - 4/25/2017

This product is great! We got the 30in because we were using the existing space from our old (electric) cooktop. Since it was not a kitchen reno, we didn't want to have to cut any granite, etc. I love the cooktop but would definitely recommend the 36inch for larger spaces (though this one is perfect for a smaller space!). We only had one issue with the knobs not being aligned, but it is covered under warranty and in the process of being fixed. It does not impact the function at all - just the look.

Yes, I recommend this product

Excellent cooktop

The black ceramic finish is easy to clean and looks great

I would buy this product again

Submitted by Cook - 4/11/2017

I have had the cook for a few weeks and do like it. It replaced a 25 year old Jennair downdraft. I like the continuous grates and the clean look of the stainless steel. I have to get used to the different burners in terms of the flame power. I have some concerns about how well the labelling for the knobs will last. There is no way to avoid cleaning the area because of spatters, but every time I clean it I expect to see less and less of the labels. I guess time will tell.
