Customer Question

Customer: ***** *****. No heat

JA: OK got it. Last thing — JustAnswer charges a fee (generally around $18) to post your type of question to HVAC Experts (you only pay if satisfied). There are a couple customers ahead of you. Are you willing to wait a bit?

Hello and thanks for using this service, if you have been waiting do not worry or get upset I am just one of the techs on here and I try to get to as many customers as I can and I just picked up your question now. Please give me time to respond sometimes I get your replies late so there may be a delay in my response.

You likely blew the low voltage 3 amp fuse in the unit, check the board for the slot fuse or check for an inline fuse on the unit to the board Now as for the code that means the pressure switch is not working right so that could be a inducer motor issue if it is not running or a clogged pressure tube or possibly a bad pressure switch you have to check that out after you get it running again.
