Have HVAC Questions? Ask an HVAC Expert for Answers
Hi, I'm Tim and I'm an HVAC expert here to assist you with your questions. Please provide all information I request as it makes it more difficult to troubleshoot something when I'm not there onsite. Essentially, you become my eyes and ears. Thanks for the opportunity to help. At the end of our dialog, you will have a chance to rate my service, but please wait until we are finished and you're satisfied you have all the information you need.
Without a model number, I won't necessarily be able to help you find a manual, but try this: use the up and down arrow buttons to set a temperature, then immediately hit the "hold" button. This should hold that temperature indefinitely. Of course if you can get me a make and model I can help you locate a manual.
Did you still need assistance with this?
Great! Did we get your issue resolved?
Let me know if you need further help to resolve this. I always strive to help my customers get their problem resolved. Otherwise, if the answer is satisfactory, thank you for using Just Answer and please don't forget to rate my service as that's how experts get paid (Thanks in advance for any bonus left). Otherwise experts work at their own time and expense. Feel free to post back with any additional questions.
