Customer Question

I have an Argo AT series 12261013 2 element boiler. I'm getting a fault light #2 which is defined as Stuck/welded element relay contact. I checked it with a multimeter and the stuck relays are for element #2.
JA: I'll do all I can to help. How long have you been dealing with this?
Customer: A few days. But my question is can I use the spare relays that are located below? There are 2 sets of spares that if it was a 4 element panel it would use them all.
JA: Do you plan on doing the work yourself?
Customer: Yes, because if this is possible it would take about 2 minutes to do. I have called a professional in the meantime. Thanks.
JA: Anything else we should know to help you best?
Customer: No, I think that's it!

If you have spare relays you can use them if they are the same spec as the damaged relay

Customer: replied 3 months ago.
They should be exactly the same specs. They are unused in the 2 element model, but the 4 element model uses them. They are located directly below and there are 2 relays for each heating element i.e 8 relays total. I'm just not sure if the circuit board will recognize them and be able to function properly, and I don't want to fry the board.
