Riello RDB2 Burner - motor sticking

Andy From Sligo

Hi there - Outside boiler, Motor seems to be sticking lately on my RDB2 burner just buzzing and going to lockout - if im lucky i can give a little tap on the housing and the motor will move and boiler will go as normal - too the side off to get to fan and although motor has a bit of resistance there its still moving backwards and forwards ok - would i be looking at trying changing capacitor first or could it just be motor itself packing up do you reckon, do caps give any kind of problems on these burners? any ideas please?

Sounds like capacitor replace it and that should

Motor sticking can be from many causes, motor, bearings, oil pump, capacitor, etc.
If you are feeling some resistance when turning the fan, the issue is most likely the oil pump. To check this, the pump needs to be removed & turn the spindle at the back of the pump. If there is the same resistance here, then the pump is faulty.

Capacitor can be tested for it's capacitance (farads).

capacitor first then fuel pump

thanks everyone for the replies - i might as well order up a cap then tomorrow, its only 12euro from this place then al least i havent broke the bank even if it turns out not to be the capacitor

Do you have a multi-meter?

thanks yes i have a digital one, i could check the resistance tomorrow - what figure should it read on the display do you know please?

Not resistance, but capacitance. Not all meters can measure this. The symbol is 2 T's lying down like this ⊣⊢

You will looking for a result of about 4.5 µF capacitance ± 5%.

ah right thanks, no only have ohms, volt, Amp, diode, and hFE (whatever that is) on my multimeter

Bout time you did the Oftec coarse Andy.

well whatdya know it started all by itself today without me having to hit it with a hammer - every time the motor/fan started with no problem and every time. So I didnt end up ordering a capacitor for it in the end.

no, but the hammer was holy, I got the local priest to bless it - it works at fixing other things as well like problems with car engines - lol

would it stop the wife from spending money I don't have

whilst I had the cover off yesterday I also got tool number: 167/100/2 out of my toolbox ... to the unqualified thats a tin of WD40!

More experienced use 3in1 or copper grease spray, due to it withstanding higher working temperatures. !!!

Part No. 3 in 1




If made by the Chinese you'll get chips, curry & rice, so a word of caution before you open your magical tool box to show your customers your latest fix it all purchase.

3in1 is popular, my son loves them.


There crap.



ps. Down here we eat meat, not our mate, (yet) !!
