How to fix simpson mini max 8 dryer.not heating?

Hi, i have simpson mini max 8 dryer, The dryer itself works but only cold air comes out of dryer when put on hot switch. We had an electrical short elsewhere in the house. The dryer was on and working/heating. When the house shorted. When the outside house fuses were fixed. The dryer just blew out cold air doesnt heat clothes anymore Can any one please tell me why it doesnt heat and how to fix it. thanks
