Bluestar split ac indoor unit making abnormal

Bluestar split ac indoor unit making abnormal noises. I have a 5 star 1 ton bluestar ac model 5HW12ZBI. It makes noise (kit -kit) when the ac trips off. The noise is minor during day time but it Ibecomes unbearable after I go to sleep after I switch off all lights in my room. The noise can be explained as machinery like something is stuck in its fan. I am unable to sleep due to this. I have consulted bluestar people....they came ...cleaned indoor & outdoor unit and went....doesnt help...and as I explained that noise is more at night so they did not get it at day time... Thanks in advance..... My email is amaranup@gmail.com.

From your details i can observe the blower motor bearing worn out. or its side bushes in which there is small bearing that may be worn out. Replace it. Finally check for correct voltage too.

SOURCE: AC doesn't blow cold air

Threr are suppose to be two sounds comming from the window unit. One, the fan sound and the compressor sounds, (this compresses the refrigerants aove room temperatures (around 240*) & send it to the back coils and remove it to room temperatures and send it to the front coils which if enough freon, it will cool to at least 40*. Turn the thermostat all the way up or down while its off and see if you hear a clicking noise which tells you the thermostat is working which that what calls for cool. If it started loosing cools little by little, then you have a leak, and leaked all the freon out! If it stopped cooling all of once, then your compressor is not kicking in.

SOURCE: fujitsu heat pump noise

i would check the blades on the condenser fan motor and make sure they are not hitting anything if they are not, spin the fan see if the fan spin freely, it should, if it doesn't it could be the bearing in the motor are dry and going bad

SOURCE: ice formation in the indoor unit

you need to have the unit checked for the amount of freon in the system this must be done with a gauge set the freon amount is obviously incorrect
also the a-frame evaporator must be sealed in the furnace cabinet

Whatis ideal r22 gas pressure required in 1 ton split ac of BlueStar.


Doesn't matter how big the unit is, pressures remain the same. On a satisfied temperature, approximately 75 degrees, r22 should be around 65 psi. The hotter the house, the higher the pressure. Head pressure varies on outdoor temperature. 90 degrees outdoor temp, approximately 200 to 225 psi on high side.

No spark and no power: Bluestar 36


Is there power at the outlet? I know that it is probably very hard to get to behind the heavy Bluestar, but it looks like you may have to pull the stove away from the wall and make sure it is still plugged into a working outlet. All of those stove functions are fairly separate, so to have all of them go out, you probably have a power supply problem. There may even be a break somewhere between the plug and where it splits off into the fan/light/ignitor parts.

No spark


Replace your Invensys U-67204-8 0+4 Module: http://www.toolbox.invensyscontrols.com/appliance/linkedElements/ElectronicSparkIgnition_SparkReignition.pdfwith a Tytronics 4 Point Re-ignitor #RI 120E-4: http://www.tytronics.com.au/__files/f/2792/4 Point Re-Igniter.pdf which has replaced the older Invensys Module on BlueStar Ranges like the RNB304BV1 - 4 Burner Range (also used in some Viking Ranges): http://bluestar-store.mwrc.net/en/product.php?product_id=40478 Call Prizer-Painter 800-449-8691 for instructions if not sure how to do this. Also, may want to do some cleaning first overall on the Burners and the Igniters - BlueStar Part #741801: http://bluestar-store.mwrc.net/en/product.php?product_id=37702 or replace if broken: http://www.bluestarcooking.com/bluestar-service-videos.html#
