Have HVAC Questions? Ask an HVAC Expert for Answers
good morning Lou.
let's see if I can help a little...... may require some testing though based on what your stating in your "tried so far".
are you online?
Do you have a multi meter for troublehooting?
You can get an inexpensive one at Walmart for about 15 bucks if you would like to troubleshoot and I would be happy to guide you.
That is probably the transformer.yes we will need meter for troubleshooting to see where we are getting or not getting power at different locations in furnace.
Lets do one thing before getting meter just to eliminate thermostat. Go to furnace and at board, jump R and W where thermostat wires connect to see if heat will come on and then R and G and see if blower will run.If not,Sounds like either an issue with the board, relay or motor, but we need to determine which.
Ok first step is let me get complete model on furnace .It will be on a label just above burners on inside right or left panel.
Below will be our sequence
1. Check for 120v AC into tansformer.
2.Check for 24 volts AC out of transformer
3. Turn thermostat to call for FAN ON. Check for 120 volts AC to blower motor from control board at terminals
I should be around tomorrow afternoon to assist with this as you go.
Sounds good,headed out to Christmas parade.Talk tomorrow.
See below for where we want to check voltage.
1.120v in to transformer
2.24v out of transformer
3.120 v to COOL and CIR-N terminals on call for fan or AC
Issue can be transformer ,board,fan ,capacitor,etc. If all those values check out the fan is bad, but lets not get ahead of ourselves.To tell you to replace a part or exactly what is wrong with your unit without troubleshooting the situation would not be doing you justice ,would be less than professional on my end and a guess at most.
Here are some general estimated wholesale costs though for parts
Transformer 10 bucks.control board 200 bucks, blower 80 bucks capactitor 10 bucks
