Replacement light bulbs for Whirlpool microwaves are available via online retailers such as Amazon.com and dedicated online appliance stores such as AppliancePartsPros.com. However, different Whirlpool microwave models may require different models and types of light bulbs.
For example, Amazon.com features a Whirlpool replacement light bulb with a model number of 8206232A. AppliancePartsPros.com has replacement light bulbs for several different models of Whirlpool and KitchenAid microwaves. To order from AppliancePartsPros.com, consumers can visit the website or call 877-477-7278 to order appliance parts. Sears also carries a Whirlpool replacement microwave light bulb; however, as of February 2015, this item was out of stock.
