    Welcome to HVAC TALK. However this site has rules against giving out technical advice to DIY'ers. I have attached a link below for your convenience.

    Here's something to think about though...

    When was the last time you had that unit cleaned and inspected?

    Now you have a problem with the unit. Fuel costs are skyrocketing.

    So why not call in a professional to repair the unit? While they are there they can clean and inspect your unit to insure a safe living environment for you and your loved ones. Not to mention, having an efficient running system could save you more than the cost of the service.

    What's your safety worth? I'm guessing more than the repair bill.

    Thanks for your understanding.

    (we can't help DIY, due to site rules )
