Is this an older unit with a spark pilot?



Customer: replied 6 years ago.
it is older but it is an electric split unit
Expert:  BillyHvac replied 6 years ago.


I understand, but the units had a sparking pilot and I was trying to differentiate between possibilities

Customer: replied 6 years ago.
how would i know if it has a sparking pilot? it does not appear to have one
Expert:  BillyHvac replied 6 years ago.


Do you have a model number?


Does it do this all the time? Or just when running?

Customer: replied 6 years ago.
the model number is XXXXX it does it just when running which was not all the the time until today, i also hear a a noise close to the same coming from the heat pump, which is a coleman brand (THE II) and it only doesw 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.


Anytime a part short cycles, it is not good.
