Hi ya'll, long time reader, first time poster, I just need to check my logic with you.
I've got an about 10 year old 5 button MasterTemp 400 with no display, connected to EasyTouch automation (using fireman switch).
I've checked the fireman switch fuse (good), shorted fireman switch (no joy).
Digging deeper I do not find 24v at the control panel, I checked the 24v transformer (at the transformer connectors): Input: 120v Output: 0v (disconnected) Continuity on both primary and secondary windings (why I'm puzzled).
Is the transformer a common point of failure with no other obvious issues/damage?
Is there anything else I should check before replacing the transformer?
Thanks for your thoughts.
