Re: SMD Resistor
The programmer is approximately 6 years old then stopped working on inspection I found 1 100uf x 50v capacitor down & a 470uf x 310v capacitor down on changing these the unit was still not turning on after checking all resistor's I found one that was showing OL
this is the one I intend to change.

SMD Resistor
I would be grateful for a little help identifying & obtaining a smd resistor it has (271) on the top which I think is a 2.7K ohms I don't know what make it is or where to purchase one in the Uk.
The resistor is from a 240v Danfoss C/Heating programmer any help would be welcome
Any Help would be most welcome

Re: curcuit problem
Okay now I have disconnected the capacitor & now I get 12vAC & 12 DC At last . I will reconnect everything back tomorrow & repost with the results So thanks a lot guys for all your valuable help it has been very much appreciated

Re: curcuit problem
I disconnected the light & the motor started turning but the fan did not. So I disconnected the motor & the fan still does not run so there in a fault some where with the DC layout???Leave a comment:

Re: curcuit problem
I am only getting 2.63v AC after the jack there is something on the circuit that is not right All diodes have been tested as well as the capacitors & all are good
The motor is only 1-2wLast edited by jimmyplumb; 02-19-2014, 10:11 AM.Leave a comment:

Re: curcuit problem
Tried it as this but does not work I have left the capacitor in as it was there at the beginning of the project. This is how it made up now...Leave a comment:

Re: curcuit problem

curcuit problem
Hi Guy's
I need some help with this circuit as it does not work. The motor should turn slowly the light should come on & the cooling fan should run but nothing is working. I have been struggling with this project for week's now as I have posted it before as Synchronous motor.
Any help would be very welcome indeed

Re: Synchronous motor
Slight mistake on previous see amended diagram also the adaptor is 240-12dc
The fuse is tested okay as well as diodes & capacitor

Synchronous motor
My daughter has given me a project as her husband seems to have messed things up. The project is a Christmas tree! stand. ie:- one that the light on it continually turn colour by means of. A 12v light, A 12v 6a synchronous motor with a coloured disk on top that spins & changes the light's colouring
The problem is her husband has been messing with the wiring & I need to
reconnect every thing but using copper strip board but I need a diagram to work to. On The original board there is 4 x 400 diodes 1 x 470 capacitor in the circuit. the power is 240-12v ac adaptor. The contents... -

Re: Reflow using heat gun - black & decker
My first attempt at reflows was with a heat gun same as a B&D
I bought a cheap drill stand & used that to give me more control over the temperature & fabricated a nozzle out off 1/2"fi x15mm compression coupling to give me more precise control & it did the job until I could buy a proper hot air stationLeave a comment:
