20 Most Recent Rangemaster Professional 90 SS (electric) Kitchen Range Questions & Answers

Use a good thermometer, if possible a probe type to check heat after oven is turned on , Now at different timing take the test while switching off oven or heating till the set levels of temperature can be marked and calibrated on the panel with the marking in place.
You can start by calibrating from 90 degrees and in steps of 30 degrees making sure it is marked with the set levels.
Thus it can be calibrated to work.

check your main panel for 240volts and again at plug in on unit,unless you have some power i.e. 120volts, you need 240volts to operate oven, also check neutral on supply line into oven/lights,thats open nothing will operate

That happens either because the timer control is faulty, or because there is a contact on the element wires or connectors, and the element is grounded.

Control board and wiring harness are tested using a multimeter.

I presume it is gas powered? They are available in all sorts of dual fuel variations. When you operate one element all the igniters spark. It sound like the igniter switch for the oven need adjusting. They normally operate on a cam so when you turn the control knob, the cam lobe runs up onto the micro-switch and then off it again creating a ignition spark on the way. It is a gas appliance, so call for service. Various other suggestions here https://www.google.com/search?q=Rangemaster+Professional%2B+oven+igniter+keeps+clicking ..

Remove the flame spreaders and rings from the 3 rings you use the most, including the faulty one. Put them in a large pan cold water, add a teaspoon of dish liquid and slowly bring to a simmer. As soon as it want to boil over, blow on it and turn the heat off. Leave it to cool. Scrub with a plastic pot brush making particular attention to the holes. You had a blocked one which is the one that directs the gas to the spark igniter. Rinse and dry them, and replace to the hobs.

The thermocouple needs replacing. That is what tells the main gas valve to open when you turn the knob.

Question edited for clarity and spelling of Model Range 'Tecnik' with a 'c'. Just lay it back over.
