Mitsubishi Air Conditioner Heating delayed start - Normal operation - Remote tutorial at  

I was literally trying to figure out why I wasn’t able to heat my living and didn’t realize the little one had the cold air on upstairs. Thanks

Thank you for validating my momentary insanity. Had to hit the reset button on the remote. Reset all settings and turned it off and again and after a few minutes it worked as advertised 🙏🏼 Thank you got your video

Another issue I just discovered is that if you have multiple indoor units coming off the same outdoor unit/pump, all the indoor units have to be on the same setting. All on heat or A/C. Can't have one on heat and another on air conditioning. Outdoor unit can only do one job at a time.

Thx for your help- temperatures took a dive - and same thing happened. Invaluable

Excellent I was very glad to get your help. I was rushing around because of work and not allowing the unit time.

Thanks for the vid dude. It's a cold morning and I was trying to figure out why the hell the warm mode wasn't "working". Thanks to your vid it turns out it's just some weird long delay lol

This is exactly what was wrong with mine! Thank you for this video. Outdoor unit can only do one job at a time.

respect for you my man, I only had to wait few minutes, thanks a lot

Thank you now I know how to work my heater. I knew I was missing a step.

Finally got it up and running. The only delays we had was because we realized we needed some extra parts (I’ll list that below) ru-vid.comUgkxihMYiJNXcHdbH-7ihymsLz61l7jVyb5O . So we have a loft where our current hvac just couldn’t seem to keep cool during the summer. We have been using a window unit since we bought this house over 6 years ago (all the houses in this neighborhood were built in the 80’s and majority of the houses built like ours use a window unit). I hate window units because they are just so noisy and the one we had really only cools one side of the loft. I had contemplated upgrading our current HVAC, but with all the rising prices these days, it would take years before saving up enough to do that. With the advice of my father-in-law (used to run an HVAC business), he recommended we get an inverter instead. We thought we bought everything we needed, but there were just a few other parts we didn’t anticipate needing (which is what caused most of our delay). My friend and father-in-law did all the work to get it installed and running and now we have nice cool air circulating nicely throughout the entire loft. It is very quiet and even the outside unit is much quieter than our main HVAC unit. Saved ourselves thousands getting this.

This is exactly what was wrong with mine! Thank you for this video.

Thanx for the video...!! I had the same problem... thanx to you it's solved now!!! Just wait 3 a 4 minutes and it will work

Thanks for this, i didn't know i had to wait 4 minutes. i thought the system was broke.

Appreciate all your help!!! Thank you

B L... Saved my pocket book AND my reputation... no service tech needed. Thanks for the video.

Wow this helped my girlfriends family a bunch! Now i look like a genius. Thank you

Legit life saver mate

thank you. another reason i've noticed is that the room temperature needs to be evidently lower to trigger the thermostat for heating. it takes about 4-5minutes to adjust and finally take on the new mode! argh

Thankyou. This worked on an Airbnb which had a new model

This was just what i was looking for! Thanks

Thank you! Worked perfectly

I have a similar unit that doesn’t react properly to cold weather. It does great in the hot stuff but not the cold.

Good bless you my friend you really help I was frezing I think my aid condition was broken

Appreciate your help!

Im going to have to contact the management of my building. We only have control of the unit via thermostat. No remote. Because, its October and the heat blinks for way longer than 30 seconds. The room never warms up (I end up turning it off), & the heat worked fine back in March when we moved here. All summer the AC worked fine. Now I'm trying to go back to the heat setting, but its not working or its taking way too long. Everyday its cold I try to cut on the heat. I have 4 units in the apartment. 1.Living room (largest) 2. one in each of the 3 bedrooms.

Can i ask, after 1 cleaning my mitsubishi mrslim, the unit start blinking the operation light and the unit is not working, what is the posible reason for this? Can you please help me about it?

Thank you so much

Negative 15 F here jn Maine and my heater stops working for 4 hours in middle of night.. now only blowing cold air ..

I have the same system and its making the weirdest clicking sound, any ideas of what it could be?

Why did this company ACs suddenly not working for sometime iam getting tensed to know the reason Please anyone can respond to this message

Thanks 👍🏻

I guess I'm lucky my apartment came with one of these included, why would anyone pay for such a complicated thing that needs to take so long to work? 😂

Can anyone help? I use my remote to turn on the system, however it isn't talking to the unit itself? The remote turns on, and I can change the settings, however the unit doesn't beep or turn on? It's only started happening in the last 2 weeks

I thought mine was broken, but it just lags

I got of these cappy units. a hair dryer is better than them

I'm having the same problem..

please dont move your hand too much that I cant see any simbolic clearly for heating mode.

Good instructions tho👌

Helpful, thank you.

Remote battery access shown at 8:00 You can usually find the user manual online for your model - just be sure not to click on sites who say to download, that can be a virus. Google "mitsubishi - your model - manual pdf" This is one example from the manualslib site which is usually a safe site www.manualslib.com/manual/467097/Mitsubishi-Electric-Mr-Slim-Msy-A24na.html
