Customer Question

I have an aprilaire thermostat, model 8365. The fan is on and I have set the heat but my apartment is not heating up. The thermostat currently reads 45. I have it set to 50 in an effort to try and bring the temp up slowly but this is not working. Any ideas?
Thank you!

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

First check and change the batteries on the thermostat if it is a battery powered unit. Second can you get to the board inside the furnace to check it for a flashing error codes?
