I am working on a baxi duo-tec 40 boiler there is no heating and hot water running fine. I've checked diverter valve and both motor and pin are operational.
This boiler is just over 4 yr old only serviced once before though. Next i want to check temperature sensor for central heating as they usually last around 3 years the question is Can i plug in new sensor outside of the housing while leaving broken one installed to see if it sparks and runs or would this throw an error on the display?
