SOURCE: message: "in recovery"

the "in recovery mode" is refering to a thing called energy recovery management its one of the features on your tstat what it does- when you are using the program on your tstat the "in recovery" starts your unit early so if the tstat is set to be 70 degrees at 8 in the morning when 8 o clock hits it will already be 70 degrees in your house you can turn this feature off if you want in the installation setup codes

SOURCE: Heater works, but only on Emergency Mode

It sounds like you have a "setback thermostat" A control intended to increase efficiency by allowing the fan to run for an adjustable amount of time after the heater turns off, whether the heater is electric or part of a heat pump. If the "setback" time is too long, the element will cool off and the fan will blow cold air. Try and locate the instructions for the thermostat and see if the "fan run time after heat turn off" is adjustable and reduce it by half. Most emergency heat circuits bypass control circuits (its an emergency, you know), and require manual control.

SOURCE: Gas Furnace Model GMH 95070,

Seems to me, the problem is not with gas, it's with the size of the duct work. 4" diameter is way to small if the entire duct work system is only 4". The trunk line may have not been sized proper,y. so the volume of heat has now been translated into high pressure, which is why the registers are noisy.
Also 6" ducts coming off a larger trunk line to each register is the norm for 1000 sq ft home.
Also, are your registers in the floor or the ceiling? Ceiling registers historically are a little noisier than floor registers. Mainly because, they're overhead and closer to your ears. But, if they were up-sized to 6", the noise would decrease quite a bit.

Hope this helps.

Can i hook up a thermostat to my hot blast wood/coal stove to control the heat in my home


Yes, you most certainly can. It depends on how handy you are and to what extent you are willing to go to make this happen. A lot will depend on how comfortable you are with electrical wiring and understanding HVAC controls and their function.

First though, this is the typical way a wood fired forced air furnace is designed to operate. There is a control transformer and relay to control either a combustion air fan (that you do not have) OR a motorized damper for combustion air that you also do not have. The relay closes on a call for heat from the thermostat and opens the damper from its minimum position to allow combustion air into the firebox. As long as there is solid fuels (wood) in the heat chamber, the fresh supply of combustion air will allow the fire to burn or begin to burn very quickly.

As the temperature in the wood furnace plenum increases, the automatic fan control will start the fan and it will run as long as the bonnet temperature is higher than the fan'on' setpoint on the fan control... Now the house warms up and the thermostat satisfies which allows the combustion air damper to spring back to the minimum position, causing the hot fire to die down due to lack of combustion air.

The now smoldering fire will not generate enough heat to keep the fan running too long, so the automatic fan control shuts the fan off until the house cools approximately 2 degrees below thermostat setpoint. The thermostat calls for heat and opens the damper and on goes the cycle....

An important item to remember is that on the automatic fan control, there is a 'limit switch' function. The motorized combustion air damper or the combustion air fan must be wired through the limit switch in case the bonnet temperature exceeds 200 degrees F. This function will then allow the damper to go to the minimum position or the combustion air fan to go off, causing the fire to cool down due to lack of adequate combustion air.

You don't want the thermostat controlling the circulating fan directly, because of two things: 1). If the fire is out, there is no heat to circulate but the thermostat wouldn't know that and it would start and run the fan continuously until a fire is built. and ....
2). You would still be running up and down the stairs monitoring the fires burn rate by opening and closing the lower door manually.

ALL the components you need are readily available from WW Grainger....basically : a fan/limit control
a thermostat
a 110v x 24v 40 va control transformer
a 24v spdt relay
20 ga. two conductor thermostat wire
24v actuator and linkages to mount to the existing combustion air damper. A bit of creativity is required here. I would not recommend retro-fitting a combustion air fan.
14-2 wg romex for wiring the fan control

Again, it depends to what extent you are willing to go to achieve the end result. Will it be exactly like a new system?? No, but it will operate a lot better than that which you describe.

2011 jeep liberty heater blows cold air


gas not diesel right?
what engine? option? size?
there are only 3 causes (and many parts to fail)
  1. engine coolant not hot at 180F or more.
  2. said coolant not flowing Through heater core (feel the 2 hoses?)
  3. air not flowing over heater coil. , damper stuck closed?

once the above is found.we can diagnose why?

the FSM covers all this , in the HVAC chapter.
say engine is hot, and core is hot.
you check the damper and its stuck closed.
?
1: controls not telling damper to move. (falling)
2: damper motor bad. (called the HVAC acuator by jeep)

on this new of car, we must scan it, the scan tool that supports
jeeps will set HVAC errors aplenty.
my innova 3160 can do that.

my FSM dont do that new a car.

or
engine not hot
heater core not hot
or damper door stuck closed on core, blocking heat.

Which direction should dampers be in order for the air to flow down? I bought a new house and all the hot air seems to be upstairs while it's freezing in the basement.


If you look at the end of most dampers, there is a line on the end of the shaft. this line when it is in line with the duct it is open, and when it is 90 degrees to duct it is closed. for most damper and motor, when it rotates clockwise it goes to open. and counterclockwise it shuts. default position on zone systems is open, most damper motor spring return to open. There is a allen set screw that anchors the motor to the shaft. to set up the motor and shaft, turn power off, unset set screw and rotate damper ccw and reanchor the set screw, repeat for all damper and associated motors.

I have a kenmore side by side. FF side too cold. Replaced t-stat and defrost timer. All settings and air flow set right. FF still too cold. T-stat set all the way down . Should be at 3 or 4


You need to provide a model number in order to look over the parts list and see what type of auto damper your model has. There are ways to test an auto damper to see if it opens and close properly. An auto damper can be electrical or mechanical. Kenmore model numbers look like this example=> 321.2345789 and can be found artound the fresh food compartment door frame.

5 Remove the edge sealing device, radiant shield supporting screws at the back bottom center of the control housing mounting screw at back, bottom center of the control housing. Slide the control housing to the right and lower the housing.
6 Disconnect the temperature control housing from electric quick disconnect.
7 Remove the temperature control housing from the refrigerator and then place on a
flat work surface.
8 Remove the auto damper control rod retainer, control rod and the slide control
gear from the auto damper control.
9 Now turn the control housing over.
10 Remove the two auto damper mounting screws, then remove the auto damper from the control housing.
11 Mark the auto damper rod about 1/4 in. from and away from the housing.
12 Uncoil the auto damper capillary tube at about 4 in.'s
13 Submerge into a glass of ice (not water). then watch for door to move to the closed
position.
14 Remove from ice and warm capillary tube with your hand. Then watch door for an opposite reaction.
15 If no movement is detected, replace the control. 61005971 Damper Control Assembly

The above is only a demostration of how to test a refrigerator with an auto that uses a capillary tube to open and close the damper. Your refrigerator will need to be identified by the correct model number to let you know what type of auto damper your model has, Post your model number and I will tell you what you will need to test yours, Thanks Sea Breeze

GE Gold Over The Cooktop Microwave condensation - help!


It sounds like insufficient air flow. The damper must be one that doesn't require too much air flow to open it.

Was the damper he used to replace it the same as supplied by GE in the install kit? Otherwise, if the new damper has too strong a spring in the door, it will restrict air flow.

The freezer is running and cold, the refrigerator seems to be getting warmer like as if the cold isn't transferring. Is there a fan suppose to be running or what?


It is quite common for a refrigerator to begin the first signs of a defrost problems once he fresh Food section begins to warm. Auto Dampers are an additional component to check while searching for the true reason for Fresh Food compartment warming. First look inside the freezer compartment and and see if there is a layer of frost building on the rear wall. If yes you will need to manually defrost unless you have anothr place to store the freezer goods. Unplug refrigerator and then remove the rear panel of freezer to get a good look at the snow covering your evaporator coils. Defrost with a hair drier. Now we need to look for the cause Auto Damper, Click here for the photo location of these parts=> MSD2756GEW Controls Section the adaptive defrost control is most likely the problem and is listed in the photo as location 13 and the auto damper

The Auto Damper model refrigerator has two controls and both have capillary sensing.

The Auto Damper controls the fresh food temperature and the Freezer Temperature
Control guides the freezer temperature. The fresh food compartment temperature is maintained by a damper assembly located at the back of the temperature control housing. Changes in air temperature cause the damper door to open and close. A control rod and gear connect the fresh
food control knob to the damper control.

Turning the fresh food control knob to the coldest position increases the flow of freezer air into the fresh food section. The freezer compartment temperature control warms at a faster rate and cools at a slower rate, increasing the compressor run time necessary to maintain a satisfied freezer temperature control.

I have a deluxe wired heat pump and am enquiring what the 2 zones" are


Debi - "2 zones" usually indicate, 2 separate areas of the house(upstairs & downstairs). But, this usually requires two separate heat pumps for each area. That is unless, you have an electronically controlled damper system in your home's duct work. If that's the case, when one area calls for heat or AC, the damper closes to the other area and vice versa. If both areas call for heat or AC, the damper stays in the neutral position.

Hope this helped you. Please let me know. Thanks.
