Error codes from American Standard Pub 18-HD32D2-8, which is a one-sheet document that came with my American Standard air-conditioner:

29 = not listed

129 = not listed

80 = HPCO Fault - problem is in outdoor unit - Desscription: High Pressure Monitor Fault (hard lock out, cycle power to reset)

91 = Communication Inactive Fault - problem is in air handler - Descriptions - COMM Bit Master Clock Error, COMM Heat/Cool Demand Error, Serial Motor Communication Inactive Error

91 = Communication Fault - problem is in furnace - Descriptions: Blower motor no COMM response, Inducer motor no COMM response, Loss of heat/cool demand, Loss of clock signal

91 = Communication Fault - problem is in outdoor unit - Descriptions: Loss of Heat/Cool Demand Message (COMM), Loss of Bit Master (Clock Signal)

91 = Communication Fault - Description: Comm line is dead and no bits have been received.

By the way, I do not recommend American Standard. I've had mine 14 months and it just blew up - the entire control panel blew. My advice to you - think about a different brand.

1. Press GO. The page containing the error will automatically be reprinted. 2. Turn the printer off and then on. 3. Reseat cables to the laser/ scanner and engine controller. Or in Add/remove uninstall the application, Then let the plug&play search for it, then in properties update driver

There is a big chance this is a line problem, contact your phone line company before trying to fix or replace your Fax modem on the MFP.

Good Luck

Hello sir ; Why don't try to replace a phone cable or check the wall jack.

I have a HP 3050 three in one and I keep getting a engine comm error

It is most probably the problem with line. Try to call from you fax machine and check the line condition.

nthemba- all the error codes you see indicates phone line condition or error at reciving fax's end. For more details you can refer to
