Hi all,
I got called out yesterday to Baxi Solo 3 50 PF.
Water circuit and pump fine.
Boiler works first time from cold but wont restart 1 minute later if switched off. If it is left running it will heat rads as per normal till preset temp is realised and wont fire up again for approx 6 hours later. Only the boiler neon light is on. Previous engineer replaced temp sensor and O/heat stats and fan and then gave up. I had a new pcb with me and slotted it in but still no luck.
The Manu instructions fault finding guide states if the fan is not working to check temp sensor, potentiometer and continity across pilot solenoid 1.5 K OHM. My test of the pilot solenoid gave me 1.1 K OHMS. Does any body know if this discrepancy can prevent a supply to the fan.
