Thank You Bob! Excellent presentation and explanation, in laymen terms , of the thermister replacement and safety precautions. A year old and replacing parts already on my split system...... Where did the quality in workmanship go too nowadays? Rhetorical question 😉
Thanks for the compliment. I do try to keep it at a level that can be understood. I used to reach auto mechanics at the dealer level whe I worked for Chrysler Corp. dealerships and could see the student's eyes glaze over when I had lost them. It is a little tougher on line as I can't see if the reader is following my example or if they are lost. Quality? Where did it go? Ya know, these companies will keep cheapening items to boost their profit margins and keep doing it until their products no longer work or last. Then they just keep it like that. Sort of the Peterson principle in reverse, where someone rises withing the company until they reach the level where they no longer are capable of doing that job. Then they stay there contributing nothing. Anyway, thank for the response.
Nicely explained... I`m seeing an occasional E4 fault. system will reset with an on/off cycle. I`m going to clean and blow out system and vents as you described... Thank you for you expertise.😁
This one will show an E4 on occasion but it automatically clears and starts cooling again. The time it waits to start cooling is about the same as the normal off cycle. We decided that as long as it comes back on that we would just leave it. It's not always there but sometimes and never stays off. So, if yours will eventually come back on by itself it may be just fine as is. Our original fault was an E4 and it never would restart until we cycled it on and off.. That sensor is the weak link on many AC units like this. Thanks for the compliment.
Hi thksvfor the videos, my ac is a comfort star with the error e4. Will it be the same sensor issue csuse i replaced the ambient temperature sensor and same problem
You will need to check with the manufacturer's code list to determine if they are the same. Many use a standard code system but I have seen a few that just did not fit in with that standard system. You will also need to find the various component values for your system. Good luck with your repairs.
How do I know which sensor ohm range I should have. Mine is a Arcticpro Portable AC with a E4 code evap freeze up. I looked for replacement thermistors and there are a few different ranges 5k, 10k, 15k I'm not sure which one to start with. Coil is not freezing up though, I even pulled the sensor off the evap tube and still has E4 code
Yes, I know what you are going through. I did this repair quite some time ago so I am a bit fuzzy on where I found the actual information. But, to find it I generally searched some diagnostics for other refrigerant units in the particular company's product line. Most, but not all, companies generally use the same valued parts when they are interchangable. I found a diagnostic video for this company's store refrigerator and the guy was using the value that I used in this video for the repair. You will just have to do some research to find the value for your particular unit. Thanks for the comment.
I really do not know. Is the E4 code the same on their products? If so, I would proceed the same as I did on this. Some companies have their own coding and not knowing if B&D use the same codes I could be sending you in the wrong direction. Wish that I could give you a better answer. While I am an AC specialist, my experience is mostly in the automotive field. I just apply my knowledge of AC systems to whatever I am working on and research how their systems are set up to work.
Thanks Bob 😊...I'm going to look at mine today I'm one that likes to work on things and not to just put it in the landfill if all possible 😀..thank you again for the help 😀 😊
I have a GE portable and the E4 comes on...like about once every half hour, then it comes back on, then another 30 minutes or an hour and the E4 comes on, then it comes back. Should I worry? Or need to do something. I drained the water yet it still cycles to the E4, but then like I said, it comes back cooling the room.
Well, the E4 indicates a possible issue that might need attention. If the unit continues to cool properly and cycles as it should, I would just live with it. I have repaired this code on another that does exactly what you are experiencing. It has never missed a beat and is cooling perfectly. You might try placing the sensor in a different location from where it is designed to fit. Or, replace with a different brand sensor if it bothers you. The choice is up to you as to trying to run down the problem or living with it as long as it is cooling. On the one that I had the code return, we just left it and the owner is happy with the performance.
@@bobamos3628 Thx Bob. Yeah, it cools the room and runs fine til the E4 comes on, which is seems to switch to fan mode, then in a few seconds or like 3 minutes the most I timed, it kicks back into cooling mode, no issues. I saw another repair expert say the same, as long as it cools, it should be fine but I will take your advice on the sensor replacement. Many thx to you and your channel. Best.
Here is a link to a thread on the Ocean Breeze AC unit with code E4. Each company may or may not use the same code system. www.fixya.com/support/t18635743-ocean_breeze_air_conditioner
It was the evap temp sensor and here is a link. Worked perfectly. Hope that this help you. www.amazon.com/gp/product/B07LGJ5QLY/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
If it responds to cold and heat it might be operating as designed. But, you need to find the actual specs to assure that it is running to specs. As electrical parts age, some will wander away from specs and can cause issues. You will also need to know what the particular air conditioner's expectations are for a given temperature.
@@bobamos3628 its an old unit, AxAir Gam-12 made in 2003. i cant find nothing, only a new model for sale and even then, no data of the OHms. thing is, it was kept for years not used. i pulled it out, ran it for 2 seconds and it was working. i put it on its back in the car and took it home. when i turned it on at home it gave me E4 at start. since then it shows E4 at start non stop. idk if putting it on its back did something or what. didnt see leeaking or smth else. the circuitboard is one with the display in plastic. i can pull the sensors out but not see the board. i somehow feel its not the sensor but not sure, and in my city there are mostly company's that mount brend new systems, not fixing old stuff
Gee, so happy to hear that... It has been a while since I did this video and my daughter said that the A/C is still working. She does get an E4 code at times but it goes away and cools without failing. So, if your E4 code pops up, I would not worry as long as the unit continues to cool. Replacing the mother board is more expensive than replacing the unit. If you could even find the board. Hey, it's an air conditioner and as long as it cools you are fine. Thanks for the comment.
Hi, For A/C units, this code generally refers to an outside coil temperature thermistor reading too high. I would start by looking for the actual temperature of that coil. The condenser coil is the one that gets warm while in operation. Make sure that it is clean and clear of dirt and any other obstructions. Air must flow through it to cool down the unit. It is the heat exchanger portion of the air conditioner. If you have a pyrometer, you might want to test it for its temperature. On you unit I do not have the specs of how hot it should be so Google it for specs. If it is not outside the temperature range, I would suspect the thermistor to be faulty. Hope this is helpful.

Glad that the video was helpful.
I'm in heat mode.There are two water outlets,one at bottom of appliance and one half way up ,which one is for heating?
Couldn't tell you as this is an Air Conditioner only unit.

I have an Ocean Breeze AC an it’s saying E4 so can u let me know what that means?

where do you get the ambient air sensor,,,

If the sensor read 4.5ohm and if i put it in water reading 10.4/11 ohm shouldnt it work while the sensor is in cold water reading 10kohm?
If it responds to cold and heat it might be operating as designed. But, you need to find the actual specs to assure that it is running to specs.
