No power at fan

[Backboiler]

Right all. Here's a teaser for you. I went to a breakdown on a Baxi Solo 2 40 PF, removed the case and combustion door then switched on...... nothing...... There was no voltage at the fan. I checked the thermostat sensor was ok and the overheat (even though the overheat light wasn't on). Any ideas?

 

[SimonJohns]

flow sensor??

 

[yo1]

Aps?
would a solo 2 have a flow sensor, heat only boilers?

 

[Backboiler]

Nope. I don't think they have one do they? I stand being corrected

 

[SimonJohns]

nope your right, no flow sensor

must be faulty pcb or stuck aps

 

[gasmarc]

check water flow switch on right hand corner with orange led hidden if thinking of same boiler

 

[Billy Bob Bob]

the solo 40 pf has no flow sensor or flow switch the solo he does,backboiler do you have mains going into the pcb?

By the way I found the fault in the end. This was real job today. Whwt would you spend the customer's money on? Bearing in mind that you can't take electrical goods back to the merchants. What one part would you opt for?

 

[Backboiler]

Yes Gasman. power light on the indicator and power going in

was the red break down connector shot??

 

[Backboiler]

Nope, keep going

 

[Billy Bob Bob]

thermistor? pcb shot? i dont know your looking at it

 

[gasmarc]

pcb if boiler has voltage in but not out presuming getting switched live if not opt for programmer, zone valve

 

[Backboiler]

Nope. I was astounded

 

[Billy Bob Bob]

dead mouse on the pcb? seen it before,wiring loom fault?

 

[gasmarc]

reverse polarity

 

[Billy Bob Bob]

reverse polarity

could be RP then a new pcb would be needed

 

[gasmarc]

was there voltage at the switched live yes/no ?

 

[Backboiler]

Nope. The fault finding flow chart was no help. Even misleading

 

[gasmarc]

neutral came out of plug

 

[Backboiler]

Yes switched live present

 

[Backboiler]

neutral came out of plug

Nope mate

 

[gasmarc]

well if there is no SWL the fault is outside the boiler

 

[Backboiler]

There was a switched live

 

[Backboiler]

Should I put you out the misery?

 

[SimonJohns]

earth fault, cleaned all earths?

 

[gasmarc]

ok SWL and permanent live present ,then follow all stats and check aps aint stuck and fuse on PCB aint blown

 

[Billy Bob Bob]

Should I put you out the misery?

please do its been 30 mins i would have fixed it by now
