Fan Heater Keeps Turning Off After About 30 Sec.

[wmoore]

I have a heater (Dimplex FX20V) installed in my bathroom which only seems to go on for about 30-40 sec and then cut's out. It's connected to a MRT-16-PC timer. The timer is set to max and dip switch set to 15-1hr 

Is it a problem with the timer or the heater itself ?

some photos

Probably overheating. Is the fan actually turning properly and pushing out a good airflow?

Do the elements glow red?.....try when it is dark to see the red glow better.

If they glow red then there is not enough air flow

Have you checked that you have wired it up correctly?

did you have the cover on when you tried it?

 (yes, done that before. cover off, overheats and trips off)

If you read the instructions and install it correctly it will be quite a bit down of the ceiling. I will say the one in my shower room is to high but that is only set on 1KW so doesn't cut out.

As batty says...

installed WRONG!!

from instructions...

It is essential to observe minimum wall mounting clearances - see

Fig. 1.

The appliance should be fitted horizontally, with the cable entry at the top

and grille at the bottom. It must be mounted not less than 1800mm above

the floor with a clearance of at least 600mm to any shelf or projecting

surface below the heater and not less than 300mm below the ceiling or

other projecting surface.

300mm is about 1 foot in old money...

from the photo that looks about 2 or 3 inches max?

I have the very same heater (just checked)  and it does the very same thing .   Theres an adjustable stat inside which I turned up and it worked over Christmas now it trips out within 30 secs - 1min.  I have it set at 2KW  as I always believe that 1KW is a slightly warm draught. 

So , although I've not looked at it again , I'd say the stats are probably faulty like many trusted brands once made in Britain  which are now not so trusted.

I fit loads of these,

make sure it is set on 1KW , in a even smallish room it will trip constantly on 2kw setting,

It was fine for 6 months though Stepps , before tripping , then it worked over Chistmas , about 4 weeks , now its playing up again .    Trouble is 1KW  doesn't seem enough to me .

The internal adjustable stat is only to knock it back to 1kW from 2kW when it gets to temperature,, the over temp stat is a little bead which is mounted right near the element

Thanks everyone for the replies. Not sure who installed it but does seem to be lack of airflow. Will talk to the landlord about it.
