DIY Repair Stuck Broken Heating Zone Valve Honeywell NO NEW PARTS V8043G1018 Teardown How it Works!

[PLEASE READ DESC. esp FAQ section] How to fix a Honeywell V8043G1018 Hot Water Hydronic Heating Zone Valve with Synchron motor at home WITHOUT BUYING ANY PARTS, WITHOUT WAITING. (or buying anything). This should work for related valves as well. Your time is valuable. Thank you for watching. You can click the chapters to skip the parts you don't need, or click the dots and select Open Transcript to read the text. There is a summary in the first 5 seconds. The valve got stuck OPEN (On), causing the zone to run continuously even when the thermostat was turned off. This was caused by the grease in the Synchron motor and gearbox drying out and becoming sticky. In this video the motor is taken apart carefully to remove old grease and relubricate it. This may also help if the valve is stuck CLOSED (off), but this can also be caused by a burnt motor or stuck valve, which you will unfortunately need to buy parts to fix. You can do this to troubleshoot. Most videos about this topic I found discuss how to REPLACE the valve/actuator/Synchron motor. However, it takes TIME and money to get replacement parts. On Amazon, the valve and motor are roughly 80-160 dollars CAD. You may want to replace it anyway if that gives you peace of mind. However, it is likely you will be able to save yourself some time, cold, and money by just fixing it. Please note that I am NOT a scientist, engineer, or HVAC professional. Real professionals will probably NOT encourage you to "repair", esp not DIY, on a component level like this, (though you don't always have a choice). Please consult a professional before attempting anything yourself, and stay safe and learn what you need to learn before attempting a project. I am not responsible for what you do with this info. YOU are. This video is not encouragement to do dangerous things yourself. 0:00 Introduction and Theory 2:39 Inside Motor 3:38 Take Apart 5:08 Cleaning Old Grease 9:35 Oil the Motor 12:50 Oil the Gears 14:37 Take Apart Mechanism 17:00 Put Together Step by Step 22:02 Before After 24:20 Ending FREQUENTLY ASKED QUESTIONS: 1) VALVE DOES NOT ACTIVATE MICROSWITCH IN MANUAL MODE: This appears to be working as designed. The valve requires the motor to push the internal mechanism further than the manual opening limit in order to contact the switch and turn on the heating. This is likely as a safety measure to prevent someone from accidentally having the heat on uncontrollably. Since the valves function correctly from the thermostat, they are likely working properly. 2) HOW CAN I TEST THE VALVE WITHOUT INSTALLING IT: You will need a 24 volt AC source. AC is very important as these will not run on DC. Connect the AC source to the motor leads (either way around is fine) and observe the valve opening all the way. Measure the terminals of the switch with a multimeter, and there should be continuity. Disconnect power and observe the valve closes all the way. Repeat continuity measurement of switch. It should be open. 3) MY QUESTION ISN'T LISTED: Please ask in the comments and I will try to answer!
