I'm having issues whit my dryer (Whirpool) model No. LER4634EQ0/ Serial No. MF4539848
3 wire 120/240Volts Motor 4 Amps. It just don't get hot I have replaced the fuse, thermostat and the heating element and still don't work, any suggestions I don't have a ohms meter around.

Have you check the dryer exhaust from dryer to where it exits unit to where it it exits house and the remove the blower housing and clean the lint cloggs out very well

Yes it's clean

Have you checked the power going to the dryer? Could be a breaker knocked or fuse blown in the breaker box or fuse panel. Good luck
