How to Find Model Number on Magic Chef Oven Hunker


Quoting the link above:

Step 1 Open the oven door. At the top, left-hand corner of the open oven, locate the model number tag.
Step 2 Check under the burners. Lift each burner on the stove off to see if the plate is underneath. Do this if the plate is not located on the inside of the oven.

Its quite an old appliance, try www.whitegoods.co.uk you will need the serial number and model number, to order the correct parts. Also ISOLATE THE APPLIANCE BEFORE DOING ANY WORK, lift up the knob for temp control some older models have a small screw under a plastic cap, others just pull off with careful leverage. Spray the rieostate with wd40, move back and forward several times when its wet, it should begin to ease, wait until the wd40 has evaporated, then try the switch. Thermostats come in various types for cookers depending on make and model, but it should be attainable.
Hope this helps you

3. 
   Order parts from appliance retailers. Call local USA appliance shops and ask if they sell parts. If so, get a price quote for your part and ask if it's in stock, or how soon it could arrive.
   
4. 
   Order from online parts dealers. Use your appliance model number and part description or part number to check online parts dealers for prices and ship times. PartSelect.com, RepairClinic.com and AppliancePartsPros.com all sell Magic Chef parts online. The Magic Chef website may also be able to provide needed parts. It also lists owners manuals, warranty information and installation instructions for their appliances (see Resources).
