Don't know what electricity supply is required

This job is for qualified person. Is not recomadet to doit yourself.

I used to have the same range with 2 electric ovens, but it is available with the lower large oven on gas and the tall oven electric.

The manual for theToledo with tall electric and large gas oven can be found here:

The manual for theToledo with both electric ovens can be found here:

The main product page for the toledo 90 can be found here:

you should be able to download manual from Rangemasters web site.

Yes. The Classic 110 is LPG convertible.

You cant convert an all gas cooker like this to LPG

You should try and reset the breaker. Press firmly to the off position then back to on. if you have a voltage meter, you can check for the 220volts at the wall. if the range still does not work, then you need local help to troubleshoot the machine.

good day,
hope this link below will solve your problem.

vinigar might work

Regardless of the clock running, if the timer is not set to zero and off, the oven will not function. See my instructions on using the timer (http://www.fixya.com/support/t1416237-timer_instructions_rangemaster_toledo) I hope that this is your problem and it will show you how to get the oven going again.

Comes on like this when switched on, hold down the left 2 buttons on the clock controls then whilst still holding them pres the right hand button
