Following a recipe typically involves the assumption that it will yield the same result every time. However, this won’t be the case if your Jade range is not working as intended. If you’ve opened the oven door an hour later only to find your potato al gratin is soupy and the cheese still unmelted, you might have a broken Jade range on your hands.
But not to worry, a Jade range that is not lighting or unevenly or overcooking foods often have simple solutions. However, if at any point you find yourself a little out of your depth in our Jade range troubleshooting charts, an authorized service technician is only a call away, and with the help of Parts Town, so are the replacement parts.
