After doing some replacement for the ac, the contactor stopped working. It won't close when I turn the ac on. when I pushed it in, the compressor was able to start.
I can't go out to find a new one until next week, and it's relly hot this weekend.
So, can I temporarily glue it closed?
And does change the contactor is enough?
Sincerely,
Alt

This doesn't necessarily mean that the contactor is bad. When you set your thermostat in the house to call for cooling, do you have voltage at the coil of the contactor? It looks like that should be the two small wires at the top colored red and white. Check the voltage there, and if you have proper voltage while calling for cooling, then it likely is a bad contactor. However, you might find that there is no voltage when calling for cooling. This would indicate a control power issue. You will need to troubleshoot the reason why you don't have any voltage there when you should.
