how do you nget front panel off dryer

2 things can cause this. 1st the felt bearing at the front that the tub rides on may be worn the 2nd is the rear bearing that the tub actually attaches into. one of these is bad or going bad.

the heater element has two parts to the heat coil if one of the coils breaks it will not get hot enough to heat the load all the way to set of the sensor to stop . it seems like you need to replace your heat element . if you want to know how to take it apart i have a couple of posts that tell how or reply back the coil costs about 89 dollars you can get one pre strung for around double the cost

Remember heat rises. However if it burns your hand or you can smell something you need to unplug the power to it asap. Most of them come with a one year in home service repair. It takes a while the heating elements to get hot in the dryer so that's probably why it seems its getting hot on top after the clothes have been in for a while.

Most likely a bad thermo-fuse also called a high limit. Not hard to fix and cost little.
Please rate solution if helpful

classical sign of a bad motor. the motor has a thermal switch on it telling the unit to shut off when it gets hot. after it cools down, the switch will tell the motor to turn back on again. good luck, i'm pretty sure that's your problem. contact me for further help if needed. thanks :)

Disconnect the vent from the back of the dryer and dry a load unvented too make sure you don't have lint built up in the vent line causing an air flow restriction.

this is an airflow problem. make sure you are using a rigid metal duct behind the machine and not a flexible one. clean out the exhaust duct behind the dryer and in the wall all the way to the  outside. any residue of lint inside these ducts will increase drying time dramatically. basically clean everywhere the air flows. 

• if you already checked this and think it is a different problem then let me know, i will help you figure it out.
