Hello, was it running OK before you decided to clean the coils, or were you trying to solve a 'not running' problem by cleaning the coils.
Cleaning the coils was a very good idea, you may have tripped over the small thermostat wire that sends 24volt power to the controls inside the unit... inspect for that.
it could have pulled loose from its terminals inside, or shorted against the sharp sheet metal edge of the opening it passes through getting inside the unit.... that fuse is on the printed circuit board that is mounted on the main blower, in the unit that is inside your house.
You will have to remove some service panels to inspect for that.
If its not a damaged 24v circuit then you will need a multi meter to do some trouble shooting with. In that case tell me a lot about hour technical skill sets so that I can coach you most efficiently.
Once we have the problem solved please locate the 'finish and rate your expert' link and click on it, that is how I earn a living, lacking that I work at my own considerable expense. Rating will not increase your charges.
Hello again, thanks for the pictures. It looks like the thermostat wires are intact, it might be an easy fix I suspect it is. but you will need a multi meter and some technical skills to handle it... we would check the power to the unit, it is possible that you put the disconnect block in backwards if that is the type of disconnect you have.
If you would like to rate my assistance I will appreciate it, locate the 'finish and rate your expert' link and click on it, lacking that I work at my own expense, rating will not increase your charges but is how I earn a living. Thanks!
