Kenmore dryer, model 110.87088601, not drying in a single cycle like it should after belt and roller replacement

[ClayC]

About a month ago I replaced all of the rollers, belt, and belt tensioner on my dryer. I also cleaned out the interior of all excess lint. 

I reassembled everything and it operates "fine" except for 1 issue - it never drys the close in one cycle anymore. 

It usually takes 2, or sometimes 3 cycles to fully dry each load. I'm assuming this might be related to the moisture sensors, but everything looks to be OK with them. 

I'm just looking for some pointers before I tear this thing back apart again. 

Thank you!

.. If it's heating but taking forever to dry 9 time out of 10 it's the vent. Maybe do a load with the vent disconnect and see what happens.

As mentioned previously, run the dryer with the vent disconnected. Feel the air exiting the dryer: if it is hot, then the dryer is fine and the vent is the problem; if it is not hot, then there is an issue with the heating circuit of the dryer. Remove the lower front panel while it is running and check for power to the heating element. Chances are the hi-limit thermostat or blower safety thermal fuse failed.

Thank you! I'll unhook the vent and see what happens. I'm pretty sure it's heating because the clothes get warm, so it makes sense if the humid air can't get out, things won't get dry.

+1 for blocked vent and also clogged up blower housing or bad blower wheel could cause slow drying.

Well, I unhooked the vent and I was getting warm, moist air out off it. I hooked it back up and checked outside and same result. Granted my vent dumps directly out of the house behind the dryer with about a 1' section of flexible duct between the two. So I don't think lack of air flow or lack of heat is the issue.

If this were a gas dryer I would 100% tell you to replace the gas valve coils, however an electric dryer does not have this weakness. The fact that you mentioned excessive lint inside the dryer points back to an airflow problem. First of all, make sure the drum was put back facing the same way that it came out. Some dryers have drums with about an inch difference between the inner diameters on each end. This would make the airflow fine outside the dryer, but would pull a lot of ambient air through the clothes instead of heated air causing long dry times. If that is not the case, then you need to take a close look at the heater tube. Check the heating element for continuity between terminals and the heater tube, and replace the thermostats on the heater tube. The heating element should have between 10-50 Ohms resistance between terminals, and infinite resistance to ground.

There are a lot of factors that can affect air flow and heat, but those are the only two options possible.

Well looks like you guys nailed it! Looks like I've got part of the heating element is bad!  I didn't even have to break out my meter for this one lol. Thank you for the help!!

At this point I won't use the dryer anymore until I get it fixed. I realize the element is finding a ground through the body of the machine because one of the leads is completely gone.
