There are so many ways to fix your dryer - and quite a few options in buying parts. You can buy individual components or in many cases, there are tune-up kits available for a great price. I recommend for noisy dryers to purchase the kit and then you only have to take it apart the one time! If you have a Whirlpool, Maytag, Roper, Inglis, Estate, Kitchenaid, Kenmore 110 or any product made by Whirlpool - we carry the 4392067 tuneup kit which has 4 drum rollers, idler, and belt (and instructions) or the 4392065 kits for the slightly older and very old styles and it too has the 2 drum rollers, belt, and idler. There are different styles used so the model is important to determine which one you may need. There are kits available for Frigidaire, Kenmore Elite, and there are kits available for the LG and Samsung, but we sell those items separately. We can help you source GE, Fisher Paykel and all kinds of brands. We carry the idler pulleys and drum rollers and belts in the original or in the aftermarket. We carry, in stock, the dryer elements for the Samsung dryer in OEM (original equipment manufacturer) or in the aftermarket and the element only or the whole assembly with housing and thermostats. DC97-14486A seems to be a popular item. If the dryer runs but does not heat, remember to check household breakers first. It runs on one breaker but needs two to heat up. Then call us or online chat to determine what you may need. If you need advice - we are here to guide you!
