No power to the pannel or unit

I plugged the unit in; it ran then it just turned itself off. I checked the plug, the breaker box and its all working and have power. I have tried to unplug, wait 3 minutes and plug it back in but I get no power on the display. Is there something that might need to be reset on the unit, and if so were it located.

Re: No power to the pannel or unit

I have the same unit and it started to act funny then eventually would not turn on. Suspect circuit board for controls.(I removed the board and played with the connector and checked the components ) All was good and unit is working again still need to find new board Part #cor182k

What can I troubleshoot to determine why my RV Rooftop Heatpump does not work on generator, only shore power?

There are a couple of possible causes:

1. There is a Front/Rear Switch somewhere in the unit, usually in the main salon or near the breaker box. This is most common if your generator is not large enough to run 2 units at the same time. It is not always labeled as such, sometimes it's just 1 or 2 and in others it's a set of breakers.

2. You have dropped a leg from the generator output. Normally the generator has 2 outputs, each feeding a separate circuit. This could be in the generator, the transfer switch or the breaker box. If you have issues with other 110v circuits, this would be a place to start.

I have a bathroom Broan 504/505 vent fan. This model just stopped working. I have power to the unit but for some reason it wont work. I pulled the fan plug from the fan housing & used an extension...

the motor is prob rated for 120-140 volts if your only getting 110 there is the problem see what the breaker is putting out at the box the light will still work but the motor needs enough amps to start sounds like a voltage drop issue

Just put air conditioner back in for the summer.. plugged it in and ran a test on it then nothing... any suggestion why it wont turn on..

Could have quite possibly tripped the circuit breaker. If it is a 230volt unit, there will be two breakers, they are usually joined together and probably 20 amp. Trip them all the way back and then all the way forward. If it is a smaller 120 volt unit there will only be one breaker, more than likely a 15 or 20 amp. Hope this works. Also, on newer models the plug may contain a reset button. It will be right on the head of the plug itself.

My Heat Surge was working fine, then it just went out. It is plugged in, but when I tried to start it again, it wouldn't light. HELP!

Tirn the Master ON/OFF switch to OFF. Unplug the unit for 12 to 15 minutes. This should allow the unit to reset itself. Plug the unit back in and turn the Master Switch to ON. If it reset itself, it should work normally. If it doesn't test the wall outlet it's plug into to make sure it still has power. Unplug the heater and plug in a lamp to see if it works. If it doesn't the circuit breaker in your homes breaker panel has been tripped and needs to be reset. More than likely, your Heat Surge Heater tripped the breaker, because of a malfunction.

Hope this helps solve your problem.

My AC unit has three wires, green, white red. Coming off the house and off the unit. How do I wire them!!

Hi, if you are talking about the wires,high voltage wires coming from the breaker box, and the same coming from the outdoor unit which are also high voltage wires, you have to set a disconnect box and mount it with in 3 to 5 feet from the outdoor unit. I am assuming you had no prior a/c unit there? If not, the 3 at the house must be ran out of your main breaker box through a breaker, double pole. It needs to match the rating of the voltage on the data plate on your unit, lets say, 30 amps. From your breaker box it needs to be ran through water tight conduit over to the box you will be adding there. Even though you have a green for ground, white and red, the white should be 120 volts and the red the same to have 220 volts. They will wire in this box to the line side. The directions in the new box will tell you line/power in and load/power out to new unit. This box you will need to buy is either a 30 amp or 60 amp disconnect. From the new unit, you will need to buy enough wire of the same size, and a piece of 3/4" seal tight flex conduit and 2- 3/4" connectors. Pull the 3 pieces of new wire through the flex conduit and connect to the 3 wires there. The green is ground so just connect it to a ground or the case. The other end will go through a knock out plug into the box and will connect to the load side. There will be a lug for the green ground. Coming from the house at the breaker box is where these 3 wires should be, and coming out of the breaker, you can use the 3/4" seal-tight to pull enough wire from there to the new box. This is what feeds your outdoor unit. This is just for the outdoor unit. The indoor unit runs on its own power source. There has to be a box mounted there also and wires pulled from the main breaker box to the indoor box. Hopefully who ever installed the unit has done all of this. If you have all of the boxes already there, just hook color to color. If you have never had a split system a/c unit at your home before and you are doing this yourself, there is a lot of high voltage wiring that has to be put in to run both the indoor and outdoor. Get back to me a let me know what you have to work with and if you have ever had a system like this before, and if you set the unit and installed the duct work.
PS If the indoor unit is gas fired, the high voltage will be 120 volts. If its a heat pump, it will be 220 volts.

Unit Turns Off

Have you checked the breaker in the breaker box to see if it's tripped? Also check the amp rating on the air conditioner and the amp rating on the breaker the unit is plugged into, the breaker may be weak or not a high enough amps or rating for the unit it's trying to power.

A/c unit not working. Have thermistat set on 65 and temp. in house is around 85. check the breaker box for the house and it have not tripped

You must make sure that there is power to both the inside unit and outside unit. Is the room air blower blowing? If not you have either a plugged filter, iced up coil, the access door is not quite closed or there is no power to the unit. Is the outside unit fan turning? If not, you either have no call from the thermostat, the fan is broken or the unit has no power to it. I would turn off the breaker to the inside unit and switch the breaker near the outside unit to off and let them sit idle for 5 minutes. Switch both breakers back on and chect to see if the outside unit turns on. Then check the indoor unit and see if this starts blowing. Let us know what you find.
