Question about Heating & Cooling

1 Answer

Radio Shack 63-1090 indoor/outdoor temperature unit. Won't give outdoor readings. Temps are cold, -5F but it always worked before. Put in new batteries in the inside and outside units, wiped outdoor sensor clean, reset both units, no outdoor readings show up on indoor unit. Just started acting up 4-5 days ago during this latest cold spell (when we want the outside temperatures the most!). Does outside sensor need to be replaced or the whole unit, or do I have to be patient and wait for it to warm. Still, it registered and listed below zero readings in the past.

According to instructions for similar systems, you have to replace batteries in the outdoor unit first, then the indoor unit and wait 10 minutes without pressing any buttons for the indoor unit to begin displaying the outdoor temperature.

SOURCE: York Mini-Split Not Cooling? : (

This can only be a gas problem.
the split units goes on on and off if a shortage of gas is involved, the chances that you would here it wont be that big for the fans would make too much noise.
get a repair man for a re gas and all is well.

Good luck.

Wouter.

SOURCE: outdoor unit will not run

Some air conditioners have a thermostat that will not allow the compressor to run below a certain out side tempature as it will cause liquit to come back into the compressor(called slugging) and damage or destroy it.

SOURCE: blinking indicate at indoor unit

reset your unit by disconnecting the power supply for 10sec. and "on " the unit for testing. if error persist you need to replace your thermistor.

SOURCE: AC not cooling during the day

Your AC cooling efficiency is low when he ambient temperature is high and naturally it cools well when the outside temperature drops.

Please remove the filter on the grill and try to clean it under the tap water and after removing all the dust fix it back to the unit. This would increase the cooling efficiency of the unit.

Your AC is also five years old. Please avoid frequent opening of doors or windows.

Ensure that the exhaust fan and the blower of your unit are functioning normal.

The technician might not have done a proper job in fixing the area where the refrigerant would have leaked out. Please check the refrigerant pressure to ensure that no further refrigerant leak has taken place. Or even servicing your unit he would have punchered the tubes resulting in very slow leak of refrigerant resulting in no cooling or less cooling. It takes around a month to feel the pinch of it and the refrigerant. One fine morning after sometime the unit will run and it would start throwing hot air instead of cool breeze!

SOURCE: One of the indoor units blows air which is not

Sounds like the metering device in the one that's not working is clogged and not letting the refrigerant flow through the coil.

Changed batteries and now cannot get an outdoor reading.how do I fix this?


  • Remove all batteries
  • Install batteries in outdoor unit
  • Make your way indoors at a leisurely pace. This allows the outdoor unit to initialize and begin sending data
  • Install batteries in indoor unit. You should see outdoor temperature displayed
In cold weather, the outdoor temperature display may disappear due to frozen batteries. At the moment my reading is - - because it is around 40 deg. F. However, in a day or two when the outdoor temperature reaches 50 deg., the outdoor temperature will be displayed again. All in all, rather whimsical.

Just put new batteries in both units but can't get the oudoor temp to show - what have ee done wrong?


Replacement has to be done in a certain order.
  • Remove all batteries
  • Install batteries in outdoor unit. Allow time for unit to initialize and begin transmitting temp.
  • Install batteries in indoor unit. You should see outdoor temperature displayed.

You may find that the outdoor temperature is not transmitted in very cold weather. Right now it is below freezing and my indoor unit is showing - - for outdoor temperature.

Why isn't outdoor temperature displayed on indoor unit?


I have a La Crosse unit right in front of me and it is showing +18 F tonight. Saturday, we are supposedly going to sub-zero.
With regard to your problem, La Crosse instructions are very specific about the battery replacement procedure. Remove all batteries from both units, then install new batteries in the outdoor unit. Allow time for the outdoor unit to "initialize" and begin sending temperature data. Install new batteries in the indoor unit and you should see the outdoor temperature displayed.

Why isn't outdoor temperature displayed?


Try repeating the initial set up procedure. Remove all batteries from outdoor and indoor units. Install known-good batteries in the outdoor unit. Allow time for the outdoor unit to begin transmitting data. Install known-good batteries in the indoor unit. You should see the outdoor temperature displayed.

IT WORKS BUT AT THE CYCLE END SUPPLY COLD AIR IS IT NORMAL?


Most air cons now have temperature sensors all over the machine. When it reaches temp on heat cycle, the machine usually shuts down both indoor and outdoor units but the indoor unit will keep running for a few minutes with the fan on only to cool the indoor unit down. This prevents the unit reading the wrong temperature. It stops the sensor(s) reading the heat from the indoor unit rather than the heat in the air in the room.

How do I get the -- away and get the outdoor temperature to work?


You may have to "reset" it by removing both indoor and outdoor unit batteries, waiting briefly, then reinstalling batteries in the outdoor unit followed by the indoor unit. After awhile, the outdoor unit should begin sending information to the indoor unit.

Charging AC by superheat and subcool
First charging a unit by superheat, this is only for Acs with an orifice or capillary tube.
Optimum superheat is 12° to 15° at the compressor or suction line outside the unit.
Hook up your gages and put a thermometer on suction line (large line), start the AC. Measure the temperature of the suction line and read the pressure on your gages. Theres a temperature scale on your gages for R-22 or R-410A the needle will show you the pressure on the outer scale and if you follow it down to the R-22 or R-410a inner scale that is the saturation temperature for that refrigerant, (you can also use a temperature pressure chart), now read the thermometer, let’s say the suction temperature( the thermometer) is 67° and the saturation temperature (the gages or temp. press. Chart), is 55°, subtract the saturation temperature from the suction temperature, 67°- 55° = 12° superheat.
Charging by Subcooling, this is for Acs with a thermostatic expansion valve, it’s common to see a sight glass on the liquid line (on these units with a sight glass just clear it, when, indoor room is at approximate set point of the thermostat). Optimum sub cooling is 12° to 15° at the outdoor unit.
Hook up your gages and put a thermometer on liquid line (small line), start the AC. Measure the temperature of the liquid line and read the pressure on your gages. Theres a temperature scale on your gages for R-22 or R-410A the needle will show you the pressure on the outer scale and if you follow it down to the R-22 or R-410a inner scale that is the saturation temperature for that refrigerant,(you can also use a temperature pressure chart), now read the thermometer, let’s say the liquid temperature( the thermometer) is 100° and the saturation temperature (the gages or temp. press. Chart), is 114°, subtract the liquid temperature from the saturation temperature, 114°- 100° = 14° subcool.

After replacing the transmitter batteries several times, I tried replacing the clock batteries. They must have been getting low. Once I put in new batteries in the clock it worked fine. Good Luck.
