Product review (5 stars): Works Great! Swap Out the Coils While You're At It
The Issue: My dryer would heat up, but was taking a long time to dry.

Since the dryer heated up, I knew the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Whirlpool-279311-Igniter-for-Dryer/dp/B004XLDCM0/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Whirlpool 279311 Igniter for Dryer</a>&nbsp;was working. That left this part, the Radiant Flame Sensor and the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Whirlpool-279834-Valve-Coil-for-Dryer/dp/B004XLDEAU/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Whirlpool 279834 Valve Coil for Dryer</a>&nbsp;as possibly being defective. Replacing both parts is  relatively inexpensive compared to a service call and once you remove the tumbler drum, both parts are relatively easy to get to and replace. I watched a video on YouTube on how to replace the parts, removed the dryer tumbler drum and swapped out the parts.

Tools Needed: You'll need a 1/4" nut driver and a Phillips-head screwdriver to remove the parts. You might need a 5/16" nut driver to remove the front of the dryer and a flat bladed screwdriver or putty knife to pop open the top.

Results: I plugged in the dryer and it heated up as expected and is working like new.
