my furnace is making a ticking or clicking noise, is it a relay?
Is this an older unit with a spark pilot?
It is older, but it is an electric split unit.
I understand, but the units had a sparking pilot and I was trying to differentiate between possibilities.
How would I know if it has a sparking pilot? It does not appear to have one.
Do you have a model number?
Does it do this all the time? Or just when running?
the model number is 517EN002, it does it just when running which was not all the time until today, I also hear a noise close to the same coming from the heat pump, which is a Coleman brand (THE II) and it only does it when calling for heat.
Normally, I would say not a big deal...things tick and make noise....but the fact you hear it in and outside could be a relay dropping in and out. And if that is the case it could very well lead to damage. I apologize for not being able to be more specific, but given the description, I would have someone check it out.
Any time a part short cycles, it is not good.
Thank you for trying anyway.
