Part No. 3871247007 to be fitted into Zanussi ZCE 7551X cooker. How do you get inside the casing to fit the new timer unit?

hi there,
can you please provide the manufacturer and model number of the microwave so we can check the available parts for this unit.
Thanks!

Should be straight forward. Contact www.espares.co.uk for the spare parts.
Hope that helps.

Disconnect from the mains.
Remove the back, slacken the clamp bolts holding the tension on the old belt next to the motor.
Fit the new belt, tighten the tension on the belt and tighten the clamp bolts.

Disconnect from any power source. Remove the outer case. Press to open the door and just beneath the open button there is a self tapping screw holding the front unit down and in the slots. Remove the screw. Remove the plugs making a note of where they all came from! (A mobile phone camera is very handy for this job).
The panel assembly will come away from the chassis now.
Unscrew the display panel and disconnect.
Fit and connect the new panel, re fit the assembly and connect the plugs, refering to your drawing/photo.
Replace the screw after fiddling around for a while getting the mechanism in the correct place.
Fit the outer case and test with 1/2 litre of water. Measure the temperature of the water in the beaker. Heat on full microwave power for 1 minute. Check the temperature.
For your machine the temperature rise should exceed 9 degrees Celcius. If it does, you have a safe microwave cooker.
Hope this helps.

you may have some wires touching inside the cooker

What you must do is calculate the total power required by the Bosch cooker. Convert it into Amperes and copper cable is roughly 10 Amperes per 1.50mm cable. What size cable feeds you cooker at present? Or
Is the maximum power calculated for the old cooker the same or more than the new cooker. If it is and the old cooker was installed by a qualified electrician observing local electricity codes, no problem get it fitted, if not consult a qualified electrician.

If you were to log on to the manufacturer's web site, I think you will be pleasantly surprised as usually one is able to download, by model number, Customer Instruction Manuals, list of Dealers, for spare parts and service, and Installation Instructions as required.

Just Google the manufacturer's name and follow the links. Make certain you are directed to the manufacturer's web site as some search engines direct you to other sites and they charge for the information that is normally free of charge.

I hope this helps.
