HEAT PUMP FROZEN UP LIKE A ICE MACHINE I MISSED UP & TOASTED THE FUSE

This residential heat pump was frozen up due to a defective defrost board. I was fully aware I could've defrosted the heat pump by running it and air-conditioning mode at the thermostat and just pulling off the O terminal but that's not the point of why I did it the way I did it. I wanted to know whether or not the control board was defective, and that would prevent this from happening again, not getting a repeat call is a whole point of the service call not just getting it running again short term.

The things I cover is....yes I made mistake and blew the fuse when I connected the jumper to the wrong terminal😱. I go into greater detail about this in my live show video. I also go into a lot more of my concerns while trying to diagnose this system. 👉👉 For those who keep repeating put it in AC mode and melt the ice that way..... That's only going to get the ice partially melted. 👉First, it's not going to melt all the ice because once it lose contact with the coil it's not going to melt any further 😲. 👉Secondly that doesn't tell me why the system froze up. But by running it in defrost mode over and over will tell me whether the system is capable of doing the job or not. It also tests the defrost board, the defrost termination switch and the refrigeration system all at once. 👉👉👉As with all of my videos, please make sure you watch the whole thing and don't skip sections then ask questions about things that were covered in the video. Thanks for watching and please consider subscribing 👍👍👍

Mine froze up once during a cold blizzard and by the next day it was unfrozen and has worked great all through the cold and worked fine last summer. I purchased a Hessaire 18.000 unit. I installed it myself early last summer. So far ( knock on wood ) It has worked flawlessly. I never realized just how easy it was to install myself. This unit replaced an OLD samsung from the 70's that stopped working. Was simple to install as the hold to the outside matched perfectly. A dealer wanted $8,000 to replace my old unit with a 12,000 btu. I paid less than a thousand with delivery. Keep up with your great and informative videos.

I was focused on why it froze and how to prevent it from happening again more than melting the ice. Hot or even cold water will melt the ice faster and completely vs any form of defrost cycle. Speed wasn't what I was looking for at that time. If I was sure what caused the ice then yes running it in cooling without the fan would have been the easiest way but wouldn't have worked fully once the ice melted and lost contact from the coil. It would have left a ice igloo around the coil.

Another fun little tip when you come upon them super frozen like that, two things right out the gate. If its a normal open/close defrost sensor You can see if it’s closed Because it should be if it’s frozen like that. Also you need to make sure you’ve got 24+ volts red to common. If it does not have power to red Or has a broken/bad common wire, the timer will never start on the defrost board and it will never initiate defrost.

If it is above 30, defrosting with a garden hose will work well, I had to do that last week! I had a friend and installed a new compressor for them in September, and I guess they did not run the A/C for the remainder of summer. I forgot to plug the reversing valve back in, and came out in November to see it covered with ice like yours is. I was able to remove the 2" of ice in a few minutes with a garden hose. Also if above 34F, unplug the compressor common wire and then run just the fan motor, the ice will go away in about 15 minutes, like a air defrost of a walk in refrigerator. Great video, I am thinking that the board and temperature sensor should have been changed, and if you don't get more no cold calls, you did the right thing.

Did you visually examine the solder-side of the 'bad' PCB? As an electronics guy, single sided boards are prone to having cracked solder joints and lifted pads. A local HVAC company wanted my mother to pay $3k for a new furnace over what was ultimately a single cold solder joint on the blower motor relay. Years before they wanted $3k for a new furnace due to repeated breaker tripping. It took me 4 minutes to diagnose a bad circuit breaker.

I know what you're saying about these other companies. I had someone with a variable speed blower that had a bad ECM, I told him to get somebody else, because he whined a little about how much it was going to be. The company who installed it came in and told them they needed to replace the whole five ton system for $12,000. I knew it just needed a blower module, which aren't really easy to get. So I went ahead and got an evergreen motor for it and fixed it. And I am an HVAC contractor, but I can't get over all these companies that won't fix anything, they just want to sell equipment and make a fortune off the customer. And I say, you'll have that with some companies. And I say it's either because they're desperate for money because of their outrageous overhead or no one knows how to fix it.
@charlessmith833 Жыл бұрын
I'm an old and seasoned electronics guy also. If you can fix the board with a simple solder repair then just do it and don't brag about it. I've done it myself more than a few times. It saves a lot of cost and frustration for everyone. Too bad the new boards have a lot of unknown parts on them which makes it hard or impossible to repair. If that's the case then scrap it and get a new one. Everything has electronics now, even my toothbrush. Ain't progress just great?

Yes but they are still nowhere near being the dominate heating method there, like gas oil and wood is, most heat pumps in Canada, just like in any other climate that can see well below freezing temperatures, are usually mated with a gas furnace or electric resistance furnace for AUX heat, since heat pumps only heat efficient to a certain degree below the freezing mark.

Demand defrost control, at least in my experience, works on a deltaT based on a defrosted coil condition. Suppose the entering ODT is 40F and the outdoor coil temperature is 32F. That’s an 8F deltaT. Then, let’s say, after running in heat mode for one hour, the entering ODT is still 40F but the coil temperature has dropped to 26F. That’s a 14F deltaT which means the defrost board will soon initiate a defrost to bring the deltaT back to 8F (or so) deltaT. It should not take very long to do this, under 6 minutes is best, in fact, too many defrost cycles longer than 6 minutes or terminating on time will create a fault. Maybe that unit is too exposed to the wind, maybe short of gas or both. It will never defrost properly under those conditions.

This is the ghetto brand 😂. This was a generic run of the mill open / closed termination defrost control. It didn't have any thermistors whatsoever, heck they didn't even have the money to put an LED on the control 😂 . As long as that defrost switch was jumped like I had it, it should have ran the full 10 minutes 🤷♂️. I haven't heard back yet so it must have been the issue.

At the end of the video it is snowing outside. What happens is the poor outdoor unit sucks in the snow, and cannot generate enough heat to remove the impacted snow. Happened to a mini split I put in for a friend. Of course we see below zero a lot so that didn't help. Whenever it snows heavy here I just turn mine off. I didn't thing I'd be using mine in the winter since I have gas heat, so I didn't put a protective shelter over it. But gas shot way way up so the heat pump is saving me money.

I just rewatched the video and it looks like you jumped between C and the top terminal (T2) instead of test (bottom terminal) and that caused a direct short on you first test. The jumper between T2 and DFT could have been left in place as it make the board think the sensor is constantly closed. When you done the test the second time you did jump C to test but the sensor was closed and that is why the unit went into defrost.

yep, but looked like he jumped middle terminal to common, instead of the top, which I think is the feed from indoor thermostat B(heat reverse), to the defrost t-stat and T2 is the other side of defrost thermostat (I may have those backwards) but jumping either top or middle to C with defrost thermostat closed will short 24v to common. whoops, did somebody forget their glasses that day lol

Watch the video again and see where the tee is at. It's before the trap, if you're going to put a tee in you put it after the trap that way you don't double trap the drain line and cause it to not drain. Also don't forget this coil is in a negative pressure zone because it's before the blower. If the coil is in a positive pressure then yeah I've put a t after it and not use a trap.

Over a year ago had to replace main board on furnace. 8 months before that it was the run capacitor on the outside unit. Just this past Monday had the blower motor replaced on furnace. When it gets a little warmer will have them come out and figure out why the outside unit freezes up on occasion. Things don't last forever, but I bet a new unit won't last close to 30 years either.

ICP, I get away with 90 mins in Florida on defrost, clearly a bad defrost board, I have not seen video yet. Mine from 2001 Heil has a thermistor to be cold enough for the defrost. That defrost board is cheap cost and other then thermostat for defrost given your symptoms that should fix it. I watched video now, that low RLA is normal when it's cold and no load on a 2.5T (it's running in cooling mode to defrost), you'd see 8 compressor plus 1 fan on a hot day in cooling. Of course you know this with your eyes closed...You where ok with board replacement even though it may have been stat only, the part does fail and in my case they came out with an improved version superseding, and it's the same board you have. In my case a lizard committed suicide on my defrost board and smoked it.

If I was in Florida market I would be using the 120 minute defrost or demand defrost (if I had a Carrier unit). The control board can't be sent back once it's been put on, this is one of many drawbacks of buying equipment from fly by night companies and expecting others to work on your equipment. I always tell my customers make sure you purchase from who you like doing business with. The company that sells the particular brand of equipment you choose will know the product best so be sure your ready to stay with them. In my area, Westinghouse and all the other Nordyne products are sold too about anyone with a contractor license. In my area Carrier, Lennox, Rheem, Trane are the big boys.
