Have a look at the actual connection from the house wiring system to the range. Pull the range out and you should see a thick cable coming from a panel in the back of the range; the cable will probably be connected to a heavy plug. If the house is an older one, there's a chance the range may be hard-wired (no connector cord and plug). With the breaker off or fuses to the range pulled, take off the cover panel where the cable enters the range. There will be a connector block with three wires leading to the cable that is powering the range - one white, one black, one red. You may see a wire that is broken off from one of the terminals - this could be the cause of the problem. Redoing the connection is not complicated, but you have to be sure to make a good and secure connection; an electrician could help you out here if necessary. If you can post a photo of anything you're not sure about, also, please don't hesitate!
If the connections look good, if you have a voltmeter, try checking across the white and black, and the white and red terminals. You should see a voltage of 115 to 120 volts for each test. Check across the red and black terminals; this should read 230 to 240 volts. You'd have to replace the fuses or click the breaker back on before these tests.
If you get no reading across either of the white and black terminals or the white and red terminals and if you had to remove a kind of cartridge that holds two tube-shaped fuses to disconnect the power, try replacing these fuses. Most hardware stores should sell replacements; be sure to buy the correct amperage ones, though. Take one of the fuses with, just to be on the safe side. Buy two fuses and replace them both. If you have a circuit breaker, there is also a possibility that the breaker itself is bad (I sent a 1974 Kenmore dryer to 'Appliance Heaven' because I didn't consider this possibility...). I'd recommend you contact an electrician to replace the breaker.
If the connections all seem OK and you can detect power from the range supply, there could still be an internal wiring issue, but do try these steps first and let us know!
