27" WP Built KM Dryers
These were pretty solid dryers, at this age it should be serviced before putting it in a new home.
Remove the lower panel and then remove the black steel lint filter housing and clean it inside, also clean the blower wheel with a tooth brush. Then clean the floor of the dryer and pay special attention to completely cleaning the motor, reach into the exhaust pipe from the back and make sure to remove any lint.
If you have the dryer outside and have access to a compressed air source you can blow out lint from the motor& blower Etc. Also be sure the lint filter has no build-up on it, if so wash with hot water and strong detergent or run it through a DW.
This is the minimum that should be done and it can all be done without complete disassembly.
