One of 2 things will stop this from running, one is a bad door switch, see if you can hold the door switch in with your hands then try to start the unit? If this does not work then you will need to replace the thermal fuse on the bower housing of the unit. The part number for the thermal fuse is(NNN) NNN-NNNN and the door switch part number is(NNN) NNN-NNNN by the description of the problem you have given me I would thing the door switch is the problem, You can order the parts you need from the following places, www.apwagner.com, www.repairclinic.com, www.searspartsdirect.com, or www.partstore.com, all of these places offer easy returns and reasonable prices for their items.
