I have acquired a westinghouse clothes dryer model # LD505EB and suspect that the capacitor needs replacing. If so it would be appreciated if someone can advise how to get to the motor. FYI the dryer which is a sensor reversing model runs for 10 to 15 minutes and then stops and the motor appears to be buzzing loudly. If you turn power off for awhile the unit will run again then do the same. Solution please.
