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 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.

Expert:  BillyHvac replied 6 years ago.

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.
