    Thanks guys, I called my service tech, and asked him to check the defrost timer and freon, as I have received many comments concerning my Goodman Heat pump freezing up and running too long on AUX heat. He did, I told him that I received the information on this site. He found that the timer was set too high, and it was low on freon. Thank you so much for your time and knowledge, I don't think he even thought to check the settings, apparently he said the factory sets them, and there is no need to recheck them. I would not have known what to have him check for, without your expert knowledge and input. Thanks again. John, now warm in Tennesse, and saving money. P.S. he to did not know because I talked to him before about this problem and he said it was normal, without looking at the unit. You guys are GREAT!!!!!!!!!!!!

The settings are for different regions. The colder your region the sooner you want it to go into defrost. If you have it set at 30 then every 30 minutes of run time the board will want to go into defrost. However there is a sensor that is mounted to the coil that registers the temp. of the coil. If the coil is not cold enough it won't let it go into defrost and the sequence starts over. The more it runs in defrost the costlier it is to run and the more wear/strain you put on the compressor and the system in general. Start at 60 and go from there.please don't forget to rate this solution. Thanks.

Thanks for your question,
as to the first part of your question, it has some variables, first the area of the country you live in, the type of system you have, how large your home is, and up to the tech to figure out how many minutes it should run in defrost, for the area I live in Defrost timers are set from 10 to 30, normally around 15 mins, the unit will only go into defrost when the defrost sensing bulb senses ice build up and will then go into defrost mode, if you live in an area where it is almost always freezing, then running the defrost for 30 mins is not a bad idea, but if its a milder climate then turning it down to 20 or 15 mins is about right, hopefully this helps you out to better understand the defrost setting on your heatpump, please rate this so we know how we did, thanks again,
mr.grzz

On carrier model 25HCB318A300 there are 3 switches to set the defrost time from 30 60 and 90 min. the diagram shows 2 switches. which 2 switches actually set the time. One has on beside it is that included...


Hello
On that model the 30 60 and 90 are times unit will be in defrost.

So depending on how long you feel the need to defrost ,set accordingly.

If this is a refrige usually 30 min is fine.If a freezer 60 min should work.

on the board there is a jumper it has writing marked 45 60 90 for amount of time to check for defrost
set jumper to shorter time if it still does not defrost there is 2 pins that you short out to make it defrost if they dont make it defrost there is a bad defrost sensor mounted on condensing coil its bad or the whole board is bad

I have a Carrier Heat pump that is iceing up in cold weather and not defrosting properly. Where is the switch to decrease the time between the defrost cycles? I understand there are 3 settings prossible...


switch for defrost is inside condenser your options are usually 30, 60, 90 minutes. you can not decrease times between defrost it is determined by a coil sensor it senses ice on coil and puts unit into be aware that heatpumps are only effecient down to certin temps.the switch you describe is length of defrost.

My heat pump will not come on in HEAT or A/C. I thought I might have a simple defrost control board problem, but still no go after replacing the board and the defrost relay. I checked the pressure switch...


Hi; Need more info. How old is the equipment,look on the outside unit data plate it will give the built date usually in the top right corner. Also heat pumps can run with a faulty defrost board. I would check for control voltage at the secondary side of the transformer should be atleast 24 volts ac. Also the test post on the defrost board are for troubleshooting a defrost problem not an operational problem.When the posts are temporarely shorted the condensor will go into a defrost cycle This step will let the tech. know if defrost is operating normally. Also I have seen a reset switch manualy reset but not reinergize the control voltage. Also the outdoor unit has a delay timer that will wait for freon press. to equalize befor letting the unit operate. One more thing do You now if Your tstat is operating normally. One more idea is the defrost sensor if faulty it can leave the condensor in a defrost state of operation. This intern will sometimes go to heat strips because they are used in the defrost cycle to warm up the air conditioning going on durring a defrost cycle. One more thought is does the control contactor have 24 to 27 volts going to it if so replace the contactor. To test this using a voltage meter and touch after waiting 5 min. both sides of the coil. Remember voltage is deadly so ..When in doubt call a qualified tech.I ASSUME NO LIABILITY FOR INJURIES TO YOU OR THE EQUIPMENT BE CAREFULL!!! IF YOU GROUND YOURSELF BETWEEN 230VOLTS THIS BE VERY BAD...alpharome416

HAD THE AIR PEEPS COME OUT THEY PUT A NEW DEFROT


The defrost timer can be set for different defrost cycles. 30, 60, 90, minutes intervals. If it does not defrost often enough or if it goes into defrost but terminates early, the unit will freeze up. One reason for early termination is the outside coil Klixon type t'stat may be bad. And as you stated, it could be wired wrong. I don't know if I'd call the same company out to look at it again. But that's your call.
Hope this helps ya.

Carrier heat pump is icing up and doesn't seem to be defrosting.


Hi, On this model of heat pump, you will have a defrost board with termination times on the face of them. There will be 1 wire plugged into one of the times, such as 15 min., 30 min., and 45min. I just wanted to let you know this and this is what determines the start and stop of defrost. You also could have a defrost timer/ defrost relay and will have a defrost thermostat located on the liquid line on the condenser coil that will also start this process if needed. This is called time and temp. defrost. On the board, there is a test point on it and will tell you on the schematic how to test this board and put it into a defrost mode very quickly just by pulling a certain marked wire plugged onto a pin and placing it on a different marked pin. This way the service tech doesn't have to set and watch for 45 min.This you can try and see if it does go into a defrost mode.If you can manually put it into a defrost, you will need a new board, as it is not going into defrost in automatic.If it doesn't, you also have a faulty board. Being that heat-pumps have so many components on them, it is difficult to walk you through all components.Heat-pumps also have 2 TXV on them (metering devices) that meter freon into the coils 1 for heat and 1 for cooling.When you are in the heat mode, the condenser coil becomes the evaperator coil with the use of the reversing valve.What actually defrosts the coil, is when it goes into defrost, the reversing valve goes into the cooling mode sending hot gas to defrost the coil.You can try and check the board if indeed it is new enough to use a defrost board and not a timer.You can look through the window of the timer also if the unit is older to see if it is moving like a clock.If not, it is more then likely your problem.You will know when it goes into defrost as the steam from the melting ice starts to rise the unit appears to be on fire. I have had calls on this. The condenser fan also stops during defrost. A faulty TXV or expansion valve as I mentioned early on if plugged or not metering can cause this also. So, I am telling you there are some things you can check on your own, and without the proper tools and freon gauges, it would be very difficult to check every componanent without being onsight. Carrier has been around for many , many years and there units are of very good quality as is Day & Night And Bryant. But, check to see if you have the board, and if you can do the tests I have asked of you. A board can be ordered on line or purchased at an appliance parts store. Please let me know what is going on with your progress. Sincerely,
Shastalaker7
PS (9 times out of 10, the defrost board is at fault or timer which ever you have.These units are difficult to trouble shoot without being onsight. Good Luck, and please let me know.

When heat is running the a/c coils freeze over with frost can you tell me the problem


The outdoor coils getting some frost on them is normal. However the system should periodically (every 30-90 mins of run time) go into "defrost" mode. Essentially it reverts back to cooling and shuts off the outdoor fan. This heats the coil outside to melt the frost. You may see some steam at this time also. Again normal. If this is not happening or not happening often enough the coil will ice up. Inside the outdoor unit is the defrost board. There is usually a pin setting for either 30-45-60 or 90 minutes. Make sure you kill the power to the unit before sticking your hands in there. Check to see what setting your is on and lower it one peg. If it's been colder and/or more humid you may need to cycle sooner. Good luck I hope this works for you. Please don't forget to give me a Fixya rating.

Goodman Heat Pump freezing up


In your climate usually the defrost timer would be on 90. However if you are in an upper elevation and it gets colder then set it at 60. what model unit do you have? Did they change both indoor and outdoor units? I would have to know the model # to tell if the fan should run in defrost. In most cases I would say no.

M#13qc-042k system will not go into defrost i replaced defrost board & sensor still no defrost


There is typically a set of jumper pins on the defrost control board that allow the system to go into defrost after 30, 60, or 90 minutes of run time. There are also two bare pins that say "test" on them. While unit is running, approx 15 min or so in heat mode, short those two pins together for about 5 seconds, this will force the unit into defrost mode. If it still does not work, you might still have a defective board. Depending on the humidity in your area, that is how you determine the defrost interval.
