We have a 5yr old Kenmore electric dryer model #84052. It does not get hot enough to completely dry the clothes. I have completely taken the dryer apart. I do not see any breaks in the element. I have a multi-meter. I am getting 240V at the wall outlet. I am trying to check the ohm resistance on each part, but I'm not sure or don't understand which reading I should be getting.

I get a reading of 0 if I check the element at both ends, I get a reading of 0 on the high-limit thermistor, and get more than a 0 reading on the thermistor that was connected to the exhaust housing. All readings were conducted with no power and no wires connected to the terminals.

Is a reading of 0 good or bad? Should I get a 0 on some parts but not others? I'm kind of at a loss because I'm not sure which part is bad. Can anyone help?
I have already cleaned out the exhaust. I even disconnected it from the dryer, turn it on, and the air coming out the back of the dryer still wasn't very hot. I can hold my hand there and it only feels warm, so I am getting some heat, just not enough.
I re-checked the element heating coils at the ends of terminals, and am getting a reading of 12. I rechecked the high-limit and the thermal limiter and am getting readings between .4 and .8. Are these too low, or should they be at 0? If they are too low, then I may just replace both parts and be done with it.
