After getting spares I was able to repair the defective one byt removing the cover, taking the spring off the armature, removing it and cleaning the copper contact area with an emery board. ?It had accumulated ¡®stuff¡¯ which came off, the relay works fine now, just be careful you don¡¯t lose the spring. ?The 10 A replacment which is programmable I could not get to work, ?no amount of turning the dials seemed to find the right combination.
To all who posted, thanks for your help.
