Over head micro wave.

[caravan john]

My micro wave is going out on overheat. I have removed the grill on the outside of the caravan. And in the orifice it seems there are some plates joined together with tape is this correct. Or could this be causing the overheat ?

To be able for anyone to offer any advice we need to know the make, model and year of the caravan, and pictures would be a great help.

Hi Prof John.
Can't see that it matters its a Russell hobbs. Made in China. Any way overheats are caused by poor ventilation around the micro wave. It 3 years old . The point I am.asking is behind the outside grill there looks like a plate and tape have been used to block off ventilation to the outside. Has any body's caravan got the same

John....

A few weeks ago my Russel Hobbs microwave in our Elddis stopped working. As a fully qualified electrical and electronics engineer I decided to investigate why and it became immediately obvious when I took the microwave out of its housing that its cooling fan at the rear had stopped working. This caused one of the two internal thermal trips to activate and shut down the microwave.

I have detailed what I did in this thread Dead Microwave

It should be easy for you to determine if you have the same problem. If it is the cooling fan then unless you are fully qualified to do so I would advise you not to take apart the microwave. It has some lethal voltages and high energy sources inside.

If you have to pay someone to get it repaired its probably going to cost more than a new one.

Hi Sam I am chief engineer electrical. You were bang on the cooling fan is kaput. Coil to the motor broken. Taken the fan and coil out.

I didn't know that Russel Hobbs made caravans

Please re read my post. ..

Because you were questioning the installation of the microwave then the model (Make and age) of caravan is highly relevant.

However I am please you have found the problem.

Not sure about your heater problem as I don't have this type.

From what you describe - hot water at first, then runs cold seems like a normal process since I'm sure its not an instantaneous water heater and needs time to recover.

Hi Sam when it runs to cold as I agree.it will.not re heat until a reset after 15mins.it seems to be looking out on some safety issue somewhere

Regards john.
