Underheating

Removed lower cover. Vacuumed out. Removed black plastic vent piece. Cleaned out piece. Inspected blower motor while there. Took unnecessary photos of element wiring. Element is on lower left backwall of dryer and can be removed from the front by removal of two hex nuts and sliding downward and then out the front. I held the new and old units side by side and transposed wires and 2 components (not sure what they are - maybe thermostat) from old to new. Reassembled easily and works great - heating better than ever.
