The temp you are looking at is a error code. 72..76 is the code for room sensor. 76..80 Room sensor shorted.

Turned to their coldest setting, most properly functioning household refrigerators can attain minus 6 to minus 10 degrees in a normal (70-78 degrees) room. Room (ambient) temperature affects cooling performance. Colder temps will cause the unit to run significantly more.

My panasonic air conditioner does not turn off when cooling


At what temperature is the thermostat?
The temperature should never be lower than 70?F (21?C) for the unit to operate properly. If your temperature setting is above 70?F, then your unit might have a problem with the temperature sensor that controls the "on/off" cycle on your unit. For that you will need a professional certified HVAC tech to inspect it.

Most people think that lowering the temperature to the minimum will cool the room faster, but that is not the case. Since HVAC units move the air at a specific rate, it can only transfer the temperature, thus cooling/heating the air, within those parameters. That's what the calculation for the BTU is for. Normally cooling/heating the room to the desired temperature should take about 1 hour, but some new inverter units can do it in only 30 minutes or so. Lowering the temperature constantly or even keeping it at the lowest setting may cause premature failure of the unit.

Dyson hot and cold fan only works in hot mode


Hi there, it's Jack at Dyson.

When you adjust the target temperature of your Dyson Hot fan heater (shown on the LED display on the base), you're setting the target temperature you would like the room heated to. The actual temperature of airflow produced by the fan heater will not vary.

If the heater won't run below 25 degrees, this is likely to be because the temperature of the room you're in is equal to or warmer than 25 degrees. The heater will only turn itself on if the temperature drops below 25 degrees, and once the room temperature reaches this target once again, the fan will turn itself back to monitoring mode.

I've attached our Getting started video below which shows how to adjust the temperature, using the remote or the controls on the base.

I hope this makes sense. It sounds as if your machine is working correctly, but if you'd like any further advice from our experts you can reach us at 0800 298 0298 (UK), 1-866-693-9766 (US), 1-877-397-6622 (CA) or 1800 239 766 (AU).

Why is my dehumidifier icing up.


The room temperature is probably too cold, or there's poor airflow
Here's some info that should help you figure out what's causing the problem:

If the evaporator coil is frosting completely and evenly, the most common cause is that the room temperature is too cold. Most dehumidifiers are not meant to be used when the room temperature drops much below 70°F and certainly not below 65°F (depending on humidity). There are however some models called "basement" dehumidifiers which are.

Another possible cause on standard models is poor air flow through the unit. If the fan motor is not turning fast enough (or at all) or the evaporator, condenser or filter (if used) being plugged can also cause this symptom .

My toyo L-30 reads the temp then Lo for instance it currently reads 70 Lo. What does this mean?


Lo is displayed when the room temperature is below 14F or the heater thinks the room is below 14F, which would be caused by a problem with the room temperature sensor or the sensor is unplugged. 70 is what you have the heater set to maintain. Check the white wire on back of the heater.

Hello, I can assist you.

If the unit is supposed to turn off and it doesn't, it will be necessary to check several things.


  • First, is the unit cooling properly? See the section entitled "The air is cool but doesn't seem cold enough."

  • Next, is the temperature of the room adequately cool? If the room temperature is cold enough try setting the thermostat to a higher temperature. If the unit then seems to work properly leave the thermostat set to the higher temperature.

  • If the unit is cooling properly when it is turned on and the room is not cool enough the problem is probably that the unit is trying to cool an area that is too large for its capacity. Use the following chart to find the appropriate size air conditioner to use:

AREA TO BE COOLED / CAPACITY (BTU/HR)

100 to 150 square feet = 5,000

150 to 250 square feet = 6,000

250 to 300 square feet = 7,000

300 to 350 square feet = 8,000

350 to 400 square feet = 9,000

400 to 450 square feet = 10,000

450 to 550 square feet = 12,000

550 to 700 square feet = 14,000

700 to 1000 square feet = 18,000

If the room is heavily shaded, reduce needed capacity by 10%

If the room receives a lot of direct sun, increase needed capacity by 10%

Add 600 Btu/Hr for each person in the room if there are more than two people

If the unit is for a kitchen, increase the capacity by 4,000-6,000 Btu/Hr.

If the room size is too big for the air conditioner you have two possible choices. Either decrease the room size by shutting some doors or partitioning off an area of the room. Or, increase the BTU of the air conditioner for that room by installing a different air conditioner with a higher BTU rating.

Here is the breakdown on this machine by temperature - it only works optimally in a room that is 68-70 degrees, which is a little on the cold side:

Freezing temperatures effect on LCD television


It shouldn't have any bad effects on the display. When LCD panels get cold they may exhibit slow response time, like trails or a persistent display when action is moving. As long as you don't experience SUDDEN temperature changes you should be OK
