Sounds like the unit either has been miswired from the beginning or there is a stuck contactor relay.

The more rare scenario is that the control wire between the t-stat and the contactor is shorting to a power source causing the relay to energize. Good Luck!

problem is not the thermostat, thermostat is an on-off switch that happens to work on temperature. Your furnace is locking out. cycling the heat off switch resets the micro-processor in the furnace. You need to diagnose the problem in the furnace, to go further we will need the model and approximate age of the unit

In some cases the fan will keep running to remove all the heat from the heat exchanger.It can be set to run shorter or longer.You might check that out.

SOURCE: Inside blower not starting every time

You have a voltage bleed somewhere or a short, whatever you want to call it. Do you have a control board on this unit where the relays are integrated into it or do you have the old type where the relay is separate? Anyway, you need to take a meter and take voltage readings to the motor when it's acting up and when it's running right. I have had the same problem with a Goodman unit before and it turned out to be the tstat! What I would do is remove the cover off the tstat and take a small jumper wire and touch the r terminal to the y terminal. If the motor starts right up, you know it's the tstat. If you have the same problem, then the only thing it can be is a low voltage short to the unit from the tstat, bad control board if you have one, or a bad relay. But if the unit is working fine in heat, it's probably not the relay. I hope this helps.

You need a new tstat. For the time being turn power off to indoor unit, remove screen, wire red, green and yellow together at the tstat and turn power back on. This will bypass tstat and should bring on the cooling. Nothing will turn it off except the breaker but at least you will have cooling. Remember to turn power off when changing tstat.

If it is an electronic thermostat it could be that the engineer has changed the board but not the sensor which reads the temp. If it is a mechanical thermostat it may be hes fitted the wrong type.It could also be that the system is short of refrigerant and the actual refrigerant charge is not getting all the way to the thermoststs sensor to switch it off, the back wall of the fridge should be frosted at least 3/4 of the way down and not just forming in a small part of the fridge.

I had a 14 seers Trane installed 18 months ago. The thermostat goes blank and the system doesnt come back on until I flip the breaker or disconnect power to the ac.


try replacing the batteries in the thermostat on your wall. probably has 2 AA's this may fix it if not may have bad or old wiring from tstat to main indoor system. when you had a trane installed did they change the air condition components only(likely) or did they put in new furnace, new wiring, new t-stat, a full install?

Won't start all of a sudden. Power is getting to the unit, no breakers thrown. Interior light works... just won't run. What do I check first? GE model DPSR475EWOWW


First, find your breaker box and locate the breaker that runs the dryer. Now flip the breaker off and then back on. Now try the dryer. If it made not change. Gain access to the back of dryer. There is a small panel toward the bottom that you can take off. After unplugging the dryer, take the little panel off. Look inside and check the belt. Make sure it is tight and still going around the motor shaft and pulley. With this model, there is a switch that turns the dryer off so that it will not run when the belt comes off. If the belt is on, you will have a bad thermal fuse and bad cycling thermostat. The thermal fuse is located on the top of the element housing and the cycling thermostat is located on the blower housing. When the cycling thermostat goes out the dryer then cycles on the thermal fuse until it goes bad. This then cuts the power on one leg of the 220V coming to the dryer. Remember, a dryer runs off of 220vs. This consist of two 110v legs. The element is the only component inside the dryer that works off of both 110v legs. Some component work off of one leg and the other component work off the other. When you loose one leg, some things will work and others will not. I hope this makes since. It's the best way I can explain it. If I can explain any of this or help anymore, please send a comment back to me.
Please rate solution and good luck.

HONEYWELLTL8230A1003 THERMOSTAT, THE SCREEN GOES BLANK THEN ON F


Well, it's an be only one of three things then (in order) -

1) Bad wiring connection, particularly the middle pair of white and black wires connected to the supply wiring, or
2) One of the breakers or fuses has tripped or blown, or
3) Bad thermostat.

If 1 is OK, check 2 (double check if breakers, sometimes they don't look tripped when they are), and lastly, take the stat back and get another one.

The ground is secondary, and it is assumed your living in a house where 14-2, 12-2, or 10-2 with ground was NOT used. If it was, hook up the ground. If not, it's OK. The grounding requirement was added to the NEC after your house or whatever was built. It is not electrically active or needed for this circuit.

Reply back what your findings are. Will be glad to help!

Readings disappear on thermostat for awhile then come back


Hi Linda,

There are a few things that cause this:

  1. When the heat is starting, it will sometimes go blank for a few minutes and then resume.
  2. Most have batteries, replace them with fresh new ones, if the electricity goes out while you are away, the batteries will keep the settings.
  3. Have someone check the house when it is extremely cold or hire a service to monitor. Your alarm company can usually add temperature sensors to your home, it will add a little safety net for you.
Hope this was helpful, please rate my answer.
Thanks,
Paul

Sounds like you either blew a transformer, have a bad circuit breaker or blew the main fuse in the outside disconnect. If the indoor unit is still blowing air (no matter what temperature) start looking at the power supply to the outdoor unit. From the circuit breaker, the power will go to a small box located within a few feet from the outside unit. This box will have either a lever on the side or you will be able to open the box and pull out the fuses. From this box the power goes to the condensor. The first thing you should do is to turn off the breaker to the outside unit. Flip it back on and if you have a call for cooling, after about 3 minutes the outdoor unit should start. If it does not, shut off power again to the unit by switching off the breaker, go outside and pull out the fuses in the disconnect box. Using a multi meter, check for continuity thru the fuses. If you have continuity, call your technician. If one or both fuses show no sign of continuity, replace the fuse(s). Make sure that the thermostat is working and sending a signal to the indoor air handler. You may be able to check this by turning the fan switch to "Fan" and see if the blower turns on. You may just have a bad thermostst. Caution should be used anytime you are near electrical components. If you do not have the skill-set required to test electrical equipment, leave it to a proffessional.
