Amana PTAC PTC093A35AA won't blow heat





 The heat has gone out on my Amana PTAC unit. I've unplugged it to reset it, but it won't work and I can't find the manual reset button. Please help me locate it.
The reset button is located behing a panel on the front of the unit that is labeled Heat Reset. If that label is gone then look around, it is a small hole, small enough for a paper clip to fit through.   

 That being said, I have 137 of these units in one of my hotels and have not had a single one needing to be reset. You probably are going to need a new control board kit. These can be purchased from Amana. They are $130. Make sure that you have pulled the heater coil out and inspected it first. Also, there was a recall years ago where Amana was supposed to contact and send out new voltage switches. These are the round black things that the Brown heater wires connect to on the upper and lower side of the heating coil. You should also try to replace those if you find the coil in good condition. I have had those resolve heating issues. Most of the heating issues were a result of a bad relay on the control board though.   

 Please remember to rate this fix.
hi, 
this is really strange behavior. the only option i see is atm to reset your preferences and check if it works again, then. 
options- > preferences -> reset preferences (left corner) 
hope that helps.

christoph thanks for getting back to me [@michel1](/u/michel1)! in this case, i recommend you to contact our support team: [how to contact our support team ✉](https://forum.asana.com/t/how-to-contact-our-support-team/87774). unfortunately i don’t have the tools in the forum to check what’s causing the error in your screenshot but our support team should be able to assist here.

when you c… Hello,  
  
Put in new batteries and try again.  
  
If new batteries did not solve the problem, the next thing to check would be the battery terminal.  
  
If
 the battery terminal is rusty, the battery power won't contact and the 
calculator won't turn on. So, use a flat small screw drive to scratch 
the battery terminal so that there would be contact.  
  
If the above
 is not the problem, the next to check would be the wire connecting the 
battery terminal to the the calculator's main board. There is a wire 
between the battery terminal and the calculator board. When the battery 
is inserted, the power from the battery goes from the terminal to the 
board through this wire. There is a possibility that this wire is cut 
in-between or is loosing contact. In this case, you need to get a small 
screw driver and carefully disassemble the calculator in order to check 
the wire.  
  
If the wire is intact, use a light brush to brush the calculator board as there might be dust on the board.  
  
If non of the above helps, then it means the calculator is dead and needs a replacement.  
  
Regards. From Kitchen Aid they only come on a new motor. I am a Kitchen Aid service agent and I remove them from burnt out motors and keep them. Look for a service agent near you and see if they can help you out. I have no idea where you are, I'm in New Zealand. re-flash bios using usb stick if you can get that far.
if not reset option and steps like clearing cmos and pins.?
new mobo or try manufacturer.. hi [@dr\_rainer\_demski](/u/dr_rainer_demski), welcome to the asana community forum :wave:t2:

in this case, i would suggest reaching out to our support team with the unique error code received as mentioned in the pop-up :slight\_smile:

you can reach out to the support team by clicking the support form prompt in the pop-up … have added psu to above post. (i added specs because i knew someone would ask. however i think it's a software issue.)

unlikely that it's the psu.

the current psu is a hx750i, and the previous psu was a hx650i. swapped over a year ago at least. this is a recent issue.


good, a lot of times this is the psu. but with an excellent unit, that's far less likely.

were you monitoring temperatures at the time? was there something specific you were doing similar in both times? really intermittent things can be hard to nail down. > Hello. I have an HP Pavilion 4500 laptop and it won't turn on. I've tried everything to get it to turn back on. There are no flashes or beeps or anything when I hit the power button. Also, before all this came up, my charger wasn't charging correctly. It would turn on then turn off repeatedly. Then one day, my laptop shut off and didn't come back on anymore. I haven't been on my laptop in about 4-5 months now. Could someone please tell me what might be wrong with my laptop?

you havent used it in almost half a year!!!! get yourself a correct charging unit for it that works properly and charge it. leave it out in a warm spot for a day before hand though. it sounds like its gotten very cold internally and also all the battery power has seeped away to nothing. this happens with rechargable batteries after a while. of course you wont get anything when you've got a dead battery. sounds like the charger you have already may be defective or your current battery is defective at least.  

At the other end of the scale though it could be that you laptops power supply unit has become defective and maybe that has blown.  

Rule out the simplest options first of it being the charger or battery. if theres no joy take it down to a local computer engineer and get them to have a look. be prepared to spend a little dosh on it.



btw what r your laptop specs?? might help us.:D hi everyone, just to close this topic, i could get a proper power supply and in fact it was the problem..

thaks everyone for your time and help ! brother, you better get a manual. i think they teach a course in this at the local community college. seriously, i can't responsibly explain the procedure to you in a venue like this.
