Why I start every dryer service with a full vent cleanout
I think a lot of techs rush to test parts when a dryer won't heat, but I always do a deep clean first. Just last week, I got a call for a dryer that was taking forever to dry clothes. Instead of pulling out my multimeter, I checked the vent hose and found it completely blocked with lint. After I cleared it out, the dryer worked perfectly without any new parts. This happens so often that I've made it my standard practice. Cleaning first can fix what looks like a big problem and save the customer cash. It also cuts down on callbacks because the real issue is gone. Next time you have a dryer acting up, try a thorough clean before anything else. You might be shocked at how well it works.
You're so right about how cleaning first can save cash. It reminds me of when my fridge was barely cooling and a friend just vacuumed the dusty coils behind it (I didn't even know that was a thing). Suddenly it was fine, and I felt like a dummy for almost calling a repair guy.
Seriously though, how often is the vent really that bad? Feels like sometimes people make a huge deal out of basic maintenance. Sure, clean it, but acting like it's a magic fix for every dryer issue is a stretch. Plenty of times the heating element is just dead and no amount of vacuuming will change that. It's good advice but not the whole story.
