Any help would be appreciated. When I put the clothes in and turn the dryer on sometimes it will blow hot. Other times it blows cold. I cleaned out the vent and any lint. If I take the low medium and high heat control and go back and forth then turn the timer to very dry cycle it will finally heat up. Although if I start it in the same settings many times it won't heat up. Thank you for any input.

While I'm no repair professional in this arena, I am capable and build and repair automated equipment. That being said, check the heating element and all your temperature control parts(all three thermostats) with a multimeter with power off and the meter on the ohms scale. The heating element should read 10 ohms and the thermostats should all read zero ohms. The cycling thermostat has two sets of tabs, and you'll be testing the outer tabs. If all are good, remove the heating element and ensure that there are no fractures that could manifest when heated and expanded. If all are still good, order a timer and replace it. The timer contacts are not designed to give many years of service, and in fact are quite light duty for the current that passes through them and they burn out after about 7 years. I hope this helps someone looking for answers, as some of the stuff I found was a bit incomplete and focused on the heating element. Good luck!

Perhaps, but still relevant, and the part about replacing the timer is one that, while quite rare, would've saved me a bit of cash and I wanted to share that with anyone else trying to repair a rather common dryer configuration, but thanks for your input.
