Water pressure good, thermostat calling for heat boiler ignites , heats to 80, turns off, drops to 40 reignites - keeps this cycle going. temp sensor? return sensor? any help appreciated


the thermostat has an upper and lower setting at which point to turn the unit off and back on
most have a 10 degree variation between off and on so that a steady temp is maintained
check to see if the lower setting can be raised closer to the 80 degrees
if not consider a new thermostat with closer settings

What is the max. temp. for 2004 4x4 trailblazer


Depends.
A normal cooling system runs between 195 degrees when the thermostat opens, to 230 degrees when the cooling fan kicks on.
If you are experiencing air temps over 90 degrees, the cooling system could run at 210 or higher.
Idling and moving make a difference too.

It sounds like you are low on charge. I think you have a thermostatic expansion valve and you need to check the subcooling, you should have 12 to 15 degrees at 95. At 95 degrees your head should be about 280# for a 12 or 13 SEER unit or higher depending on the effeciency. At 78 to 80 degrees indoor depending on the humidity, that is normal. The valve will open to try to fully feed your indoor coil and it sounds like your head pressure is to low to force enough refrigerant thru the coil.

Thermostat resets itself to 85 degrees a couple hours after I set it to 74 degrees


To manually operate the thermostat set the system to cool and fan to auto then press the HOLD button one time then release, you will see the hold word on the screen after that up the UP or DOWN arrows is setting the desired temperature.

AC Thermostat is set to 78 but wont cool past 79 or 80


If your unit is running 24/7 you are either low on charge or the unit is to small for your house.
A 20° temperature difference is about normal for the room air vs the air coming out of the ducts, but the room air and the leaving air should keep getting colder and colder.
An air conditioner should cycle approximately 3 maybe 4 times in an hour if it's properly sized.
As for the thermostat thermometer they are very cheap and are more for reference than actual temperature, so if 78° is not comfortable, then you should set it lower but not rely on thermostat being accurate or what the thermometer is saying as long as it is consistent.
The air conditioner and thermostat can also be set below 78°, there's a lot of people set them at 72° and below with no problems.
the only thing is if you have real low humidity you'll need to watch indoor coil or the suction line (the big line) on your outdoor unit and make sure it doesn't freeze up on you.

No warm air only cold with setting at 80 degrees or higher.


There thermostat is bad. If you pull off your front cover there schould be four screws. The thermostat is on the coil itself. Take that to the local appliance store and they should be able to give you a replacement part. Part is around 35 dollars or so

What tempratues should be set on a honywell 4 cycle thermost during the summer months


As a general rule set your t.sat 20 degrees below outside temp. Leave at this setting 30-45 minutes. Move down until comfortable no lower than 10 degrees below outside for 30-45 minutes. Unit should cycle normally. If it runs continuously then raise the t.stat 3 or 4 degrees up. The national average is 75-78. I usually keep mine set at 80 during the day here in Georgia and 74-78 at night...
