AC Trouble Shooting

select-fire
Ran into a problem yesterday around noon. Heat pump quit.Split system.Would not run. Fan would not come on only if I bumped the contacts. Went and got a new capacitor changed it out to no avail. Called my service man. He is 50 mile away and will catch the call on the way home around 7. He located the issue and got me up and running so anyone want to take a guess what it was? I have never had the issue until now

    This time of year I'd be looking for a plugged filter/intake or condenser, pollen. Which is likely to trip a safety, overpressure, overheating or maybe low airflow. Different rigs have different safety setups.

    Close... over flow pan in the attic has a safety switch that shuts off the unit if the drain becomes plugged.

    Make sure that switch works EVERY time. My uncle had a malfunction that flooded his house while he was gone for the weekend. Ruined a lot of wallboard, carpet, and laminated flooring. It took over a week to dry the place out.

    My oldest daughter had the same thing happen, it took out the sheetrock on one wall on two floors.

    Over flow switch. It only functions if the drain line is plugged and pan fills up.

    Those drain lines get plugged fairly often, dust, pollen, pond scum etc. Ants and Bees will get in there in a drought.

    Mine is in the attic. Split system. Cleaned out pan and drain, threw some bleach in there and it is flowing fine.

    When I worked for a HVAC company the owner insisted that we blow those out and check the P trap. Back in the day we could use R-22 :)
