Troubleshooting the Goodman Defrost Board

Wow finally someone I understand great job sir

Great overview here on a basic rundown of these Goodman Defrost temp boards. Got my sub 👍

One of the best videos that help me out in the feild

Thank you ! I was able to help my in-laws in Vegas 115 degrees , conned the last 4x on a new unit .I subscribed and look forward to more videos nice to know there's still people that want to help

great video, I like your teaching. Thanks

Can you make a video to how to bypass,thanks that’s helpful awesome video

Solid!

great work I love your teaching

I need you help bro. Checked the low and high pressure switch. Im getting 24v out abd and back in. My issue is my unit run for 20-30 mins. Then it starts cutting on and shutting off every 2-3 mins. I lose the 24v from the cnt terminal. Is the relay possibly bad on the board.

gonna put it to th etest. where do you flounder gig, I am in Wilmington, NC..

What if your control board keeps burning out
Where r24-r23-r22-r15-c1 are

Excellent. Thanks.

You are the best teacher

Perfect!
very clear explanation
Thank you!

I'll take a time temperature over a demand any day of the week. Why u might ask? ()RELIABILITY). If it ain't broke don't fix it.

Keep it simple is a good idea, these new boards are problematic , ie all techs can tell u story's about example Ameristar boards.

Hey when my unit goes to defrost the strips are not coming on I haven't checked them.out in the air handler to make sure a sequencer or strip overload etc is bad but I changed the defrost board thinking it was bad when I put it on it never would go into defrost at all . Can you tell me why? The unit is Armstrong SHp12E 30 A -1A old board like the old goodman. New board in pic.

I checked my temperature sensor in it seems that even when it's below 30 it remained open so I also check if I jump the DFT pins and put it in test it worked fine and defrosted. After I installed the new temp sensor the next morning cold out I was not defrosting again do you think I also have a bad defrost board maybe a relay sticking or something when it gets cold?

Thank you, you're videos are great.

The board has to accumulate so much run time before it will defrost.

👍 the best.

Really great job explaining how this type of defrost board.functions.

Can you replace the old board b12260-08 with the new board pcbdm133s

If this board goes out would it stop the outside unit completely? The inside unit is running the outside is not, it's not running on air conditioning or heat pump.

Replaced t stat, worked for 5 days now nothing. Tech came out said bad board. Replaced board still nothing help!!

I have a GSZ160601BD outdoor unit with this same board in it (it's a goodman unit). I also have a AVPTC61D14BA air handler indoor unit. There is SUPPOSED to be a way to hook up the outdoor unit with 2 wires, but I cannot figure out WHERE the 2 data lines connect to the outdoor unit. PLEASE HELP! This is supposed to be a communicating setup but who ever installed this thing didn't do it correctly. I have the newer board by the way.

Man my Goodman 2 1/2 ton heat pump seems to be hitting a defrost step every time the compressor runs to make heat....the compressor starts then the fan turns off.....then as the air shoots through the fan comes on and all is normal....but it does it every time

The norm or delay is for a soft start in defrost. It shuts off the compressior off for 30 seconds when switching form heat to defrost and when switching back

This are the best step by step tutorial ever thank u. 👍🏽

I literally only came here to say that your video showed up on my feed randomly, and I read the title as "Troubleshooting the Goddamn Defrost Board"

Thank you so much for making videos like this one! Huge blessing brother!!!

Great video like always keep them coming ,I love all of your videos 🙏🏻thank you for sharing your kills with us

Thank you John , Im the owner of a New Goodman System. Found out you can get the OEM Goodman Defrost Board on Amazon for around $46 . AC Company wanted to charge me $400 ! Oh my , thanks. New Subscriber. God Bless 🙏🇺🇸

Good video and explanation! One critique: I think the norm/delay jumper is a setting to allow for a delay in order to shift the reversing valve before the compressor comes on for quieter operation. I think normal just sends it

Great video brother 💯💯💯💯

Excellent video. Someone please correct me if I'm wrong here because I just did this: Y is power-in that passed through the low-pressure switch, and PS2 and R-PSI are for the high-pressure switch. You could disconnect PS2, R-PSI, CNT, and then connect Y to the contactor in place of the CNT wire and it should work fine (minus high-pressure protection). I don't think I'd want to do it that way as a contractor, but not a big deal in this case.

I'd disconnected the PS2 and R-PSI wires earlier this year to get it working again even though the pressure switch itself seemed to be fine, and then today pretty much just bypassed that whole relay.

The original board is very reliable and rarely needs replaced. Ive seen them 20+ yrs old and still 100% operational

What is a possible cause of those 3 grey resistor's being burnt down by the board??

Goodman GSZ160301 Unit pops a 3amp fuse in the air handler as soon as the power is turned on. Tested all low voltage wires for a short, nothing shorted. Would this board cause the fuse to short if its bad?

What a great video thank you for sharing wow spectacular

Excellent video. Top shelf information.

I has same board in my heat pump(Goodman)..For some reason r22 and r23 resistor is overhearing, and a/c not working, stay in heat mode..

Good video 👍 Thanks

Nice video, goodmans defrost test is a little different, you can put the jumper on test, then jump out the DFS that's if your coil is above 32F , next important part once you hear the unit go into a defrost pull off the test pin jumper and it will go into a full defrost cycle. Hope this helps anyone.

Thank you for the video. My unit is not turning the Aux heat on while it is defrosting. I will do the check in a couple of hours. It is 13°F outside.

This video was very very very useful. I really appreciate John🙂

great video. Thx
I have had 2 new boards (PCBDM133 which you show here) show sign of overheating on rge R22 and R23 resistors, with discoloration on both sides of the board. What would this indicate, is this a common occurence due to,say, improper choice of the the resistor not allowing for proper dissipation, or would this point to a differnt issue altogether ?

Thank you for the concise instructions on this board. Mine would not turn system on after power outage and kept blowing air handler fuse. Isolated issue to outside board thanks to this video.

Someone installed my ac/heat pump that shouldn’t operate a toaster. What will the unit due under heater conditions is the jumper for the 30-60-90 pins is not installed on any of them? I can’t find an answer anywhere.
