Hi, First, carefully remove your tank lid, and place it where it won't break or fall. Look for a four-digit number located on the back of the tank, near the water level mark. This is your tank model number. If the number starts with a two, it is a one-piece toilet. Then....visit this link: https://www.americanstandard-us.com/parts-support/faqs/toilets Good Luck!

low pressure cut out. refrigerant leak

american standard error of 156... on a car? If PO0156, thats an ODB2 sensor... possibly the second O2 sensor on your emission system. You can reset the code and see if within 100 miles it lights back up... Likely it will. You may have a burned out catalytic converter... or a bad O2 sensor... or a blown head gasket, or many other things. If that is the ONLY code I would go forward with the O2 sensor. Look it up on ebay, year, make and model of car. Typically if one o2 goes, the other will follow. It is symptomatic of the cat going out though. How many miles on the car? More than 150,000? Likely its the catalytic converter. They are a consumable in your car. It will affect your mileage significantly while the code is on, and typically if it is the o2 sensor itself that has gone bad ( between 30 and 100$ per) and the cat is ok, if you don't fix the o2 sensor, the cat will burn up (cost between 200 and 700, and a bunch to swap out) Get it checked out, you're looking at more bucks the longer you wait

are you running a schedule? try the permanent hold!!

you have a heat pump with 1 stage auxiliary heat with 1 stage of cooling. wire the same way

Google tcont800 installation manual. option530 should be 0 not 1. Press system button, 2 and 4 square hold until screen changes, option 530 --0

Could be a number of things:
Could be as simple as having bad batteries in your thermostat “ if applicable” some thermostats do not have batteries.

Could have a programming error “ this could happen from a power surge or outage. In this case the thermostat would need to be reprogrammed.
Could have a bad thermostat.

Could have a short on the heat pump itself.

Could possibly be none of the above, though I would trouble shoot in this order.

After checking batteries and programming I would suggest contacting a trained HVAC technician to further diagnose the issue.

Your question makes no sense. You dont have a heat pump with ONLY emergency heat. Is it working or not???

This lights blinks a sort of Morse code, a number that corresponds to a chart located somewhere on the furnace. It's usually on the doors that you remove from the front. For example, a "dot...dot...pause...dot...dot...pause" would be the number 2, which the chart may say indicates something like "ignition failure" or "pressure switch open."

Would need more info, which door are you talking about? Blower door with power switch? At what point in the firing sequence does the unit fail? So the burners ignite?

water level to low or drain partial clog

More likely the sensor has malfunctioned.

these are called phantom flushes. the water is slowly leaking around flapper or the is a scratch of the flapper seat. I use fluidmaster parts

mixing valve and ceramic washers are defective. American Standard is not what it used to be. Parts are substandard and imported from china. Get yourself a Glacier Bay, and contact American Standard and demand your money back or a credit.
