Baxi Boiler Back Boiler Solenoid


Postby Cadman » Mon Aug 18, 2008 3:34 pm

Hi

Suspect solenoid for gas to back boiler. Power to coil but valve not energising. No reading of continuity through coil. Obtained fire /boiler from ebay. This system has not been installed/fired although Baxi Bermuda 572 is very old model spares now obsolete. I was hoping that the solenoid on replacement was going to solve the problem. On checking the coil there is no reading across it. Does that mean I am stumped or is it possible I am missing something.

Any help/advice would be appreciated

I think you have posted in wrong section and are more likely to get help in Central Heating & Air conditioning & ventilating section.
My understanding of a gas valve is the solenoid is operated by a thermal voltaic unit through some mineral insulated cable and the "Super Universal Thermocouple" as it is called by Screwfix is sold for around a £5 and is normally the problem.
I have also been told although this is electrical is should be changed by a Corgi or what ever the firm is called that replaces them registered personal.
So with exception of my boiler at home I have kept clear.

You wont get a reading of continuity throught the coil, but you will get a resistance reading on the Ohms scale. I am not familiar with the baxi 572 do you mean 552?
