Ok so my heat usually works just fine, but sometimes when the thermostat clicks on I hear the system humming like it's trying to start, but just can't.
Sometimes turning it off for a few minutes and back on does the trick, other times I have to boots the temp to say 78 when it's only registering 71 inside just to get it past the humming of trying to start to actually get it running.
currently at 78 it doesn't seem like it's even coming out all that hot atm. What can I do?
The humming you hear,is that after the flame comes on ,or doesn't the flame come on.Without much info all we could say is check and make sure all electrical connectings are tight.Check and make sure you have 24 volts.Check ande make sure that the motor capsitor is ok.
Oh and when you are cdhecking for tight wires make sure you check the wires at the stat too.
