July 27, 2025Heat pump repair
I do. Most guys don't know how they work or how to diagnose, so will tell you to replace as an auto response. Repairs can be really expensive. Depending on the fault, if the unit is over 10 years old it may be better to replace. Noone repairs the electronics here. I looked in to it myself but it didn't really seem realistic the price I would want to charge vs buying a new PCB. For old units that I can't get parts for anymore I have sent PCBs to a place called module repair in Aus a couple of times. More on reddit.com

r/HVAC on Reddit: Daikin HVAC F3 Fault Code Advice
April 13, 2018 -
Hello guys!
My Daikin heating & cooling system recently stopped working and the solid green light turned into a blinking green light. With some quick googling, I found a video on how to diagnose the HVAC system and find the fault code using the remote control.
After scrolling through the codes, there was a solid long beep on F3, indicating that that's the fault. According to https://www.daikin.com/products/ac/services/error_codes/pdf/sm-ts3_p1-6_errorcode.pdf, the F3 fault code indicates a "Malfunction of discharge pipe temperature".
After getting quotes from different HVAC repair businesses in my area, I quickly found out that the prices are in the hundreds of dollars just to come out and diagnose the problem. Then perhaps weeks for the parts to get in if there was a special parts needed.
Which brings me to the reddit /HVAC community. I was wondering if any of you guys know if there was a guide on how to fix the F3 error code myself, or if it's best for me to just shell out the hundred of dollars for a trained technician to come out and attempt to fix it.
Thank you in advance for your help!

Malfunction of discharge sensor sounds like it might just be open or way out of range. if you have a multimeter you can check resistance on it. you'll have to find what k thermistor it is and find a chart and compare it to temperature. if it's just open you'll immediately know it's bad since it'll show OL. if it checks fine either something is causing it to overheat (typically power on/off resets and runs for a while then trips) or if it checks fine and go off right away potentially a board issue.
