That's the lightbulb for me. I bought one from a local store about a year ago and it was the only replacement bulb that actually lasted more than 2-3 months. One $5 a year lightbulb is better than 4 $5 a year lightbulbs! So the design of this hot tub model has a poor stock of most replacement bulbs. Whirlpool has to sell its products for quality control purposes. I'm hesitant to buy a future Whirlpool microwave (other brands don't burn through as quickly). I was distracted. LAUGH OUT LOUD.
