I recently bought an Aga Rangemaster 90cm range cooker with induction cook top. The oven and hob are great except when attempting deep frying, which seems not to work. I have nothing but induction compatible cookware.

The pans initially heat up fine, but refuse to come up to anything above approximately 150C (300F). Monitoring the temperature with a remote thermometer I can see the temperature cycling as the element comes on and off, but I am never able to get the pan up to say 180C.

I have reviewed the operating instructions and no mention is made of it not being possible to deep fry, so I wondered if this is something that others have experienced, or if there is some workaround.
