Have HVAC Questions? Ask an HVAC Expert for Answers
Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am GURU an extremely experienced tech on here and I try to get to as many customers as I can. I just picked up your question now.
Please allow time for me to respond, sometimes I get the questions or responses late so please be patient as I have no control over the site issues. NOTE, I have nothing to do with your payment to the site and personally did not receive that money. The only way I am credited is when you use the STAR/VOTE RATING SYSTEM at the top of your page. Lastly when we are done please post to me that you would like me "GURU" credited before supply the rating so there is no confusion on the tech to be credited for the question. Thank you!
You likely have blown the fuse on the board in the furnace. You need to get to the furnace or air handler and remove the panels. Once off you will see the board, check the 3-5amp slot fuse on the board and replace it if blown. That will kill power to the thermostat.
Check the 5 amp fuse on the board it is likely blown.
The only way I receive any credit at all for my time is by you selecting a STAR USING THE 5 STAR or VOTING RATING SYSTEM AT THE TOP OF YOUR PAGE before you leave for me so please make sure you are rating me not another tech. If you are not happy with the service please let me know before leaving a negative rating. This will also allow you to get directly back to me for FREE follow up questions and tips are greatly appreciated! Thanks GURU
On the low voltage transformer do you have power from the C to the 230? If not you need to check the power to the unit itself. You may have blown a breaker
No I will be offline by then
Yes if you have no power there you have a power issue from the source itself. That is really all it can be and should be easy to find.
Do you have a volt meter?
Let me send you an offer if you want me to wait.
I will be leaving shortly and I see you have not accepted the offer. If you need help in the morning I will be around.
If you want me to stay on until you get back you would have to Accept the Offer within the next couple minutes or I will be going offline.
Ok no problem I have been working all day about 18 hours so worth my while would have to be worth something decent. Thanks though and I will be on in the morning.
Just post back in the morning.
No problem talk to you soon/
