Question about Honeywell CT87B ROUND HEATING&COOLING MECHANICAL THERMOSTAT - WHITE Heater

1 Answer

Furnace thermostat I don't think my thermostat is working properly. It is an older dial type. Square body and non progammable. I don't find it in the product listing so I picked the honeywell round mechanical choice so it would let me post my question. I have taken the canned air and blew out the dust and used a soft bristled tooth brush on parts. Can you tell me how to troubleshoot it?

Get to the wiring at the thermostat. Take a small jumber wire and jump from R to G on the thermostat. Hold it there a few minutes to see if the system starts heating. If it does, you have a bad thermostat. If not, you have other issues.

Wiring instruction for a White Rodgers 1F78 non-programable thermostat.


The White-Rogers 1F78 thermostat is a single stage 5/2 day programmable thermostat. Home Depot has the manuals for one model of this thermostat, 1F78-151, on the product page: https://www.homedepot.com/p/White-Rodgers-Single-Stage-Digital-5-2-Day-Programmable-Thermostat-1F78-151/202771121 . The wiring diagrams are in the Installation manual. The direct link to this manual is https://www.homedepot.com/catalog/pdfimages/f9/f955280d-67a2-4502-bb94-4975cd857c0b.pdf . Emerson Climate also has the wiring diagram here: http://www.emersonclimate.com/Documents/White-Rodgers/instruction_sheets/0037-6615.pdf .

If you have a different White-Rodgers 1F78 thermostat, check for the manual at Emerson Climate by starting at http://climate.emerson.com/en-us/products/thermostats/thermostat-manuals . Click on the Enter Model Number button and start typing in the model in the search box. I found a number of models with 1F78 listed. After selecting a specific model, I found a link to the installation guide on the left side of the page, below the search box. (Note: the manual link was above the Suggested Replacement header for the models that I checked.)

I hope this helps.

Why won't thermostat turn on after I changed the batteries?




I think you may have the model # incorrect, However if you have a thermostat as in the type that are hand held, polarity of the batteries is the 1st thing I would check, then test them for proper voltage, corrosion will often interrupt that small of a voltage, clean the terminals and test it .




A wall mounted like a central HVAC system typically will not require batteries to operate, this is for memory and they will work fine even if no batteries are installed, however there are battery powered stats too, meaning non parasitic type that not powered by the transformer in the air handler.
I will include a basic drawing of a residential HVAC thermostat to show you how the 24 volts powers most thermostats.

I have a Kelvinator Fridge P120 Product Code: 10325 and we have no manual for the defrost or temperature dial settings can you help me with a pdf Manual?


Hi Aaron, Apparently this is a Fisher & Paykel fridge made by Kelvinator.

F&P has a support page for manuals, etc., here. I found a fridge / freezer user manual, here. F&P maintains that this manual is applicable to all of their fridge / freezers, so don't be put off by all the model numbers covered (the P120 model is specifically listed however).

If this is not the correct product, please let me know & I'll see if I can find the one for your appliance. I hope this helps and good luck!

How do I set the time on an old Regina pocket watch. I can wind it and it runs well. The piece to wind the watch does not pull in or out to set the hands.


If you can wind your pocket watch using the crown, but you cannot see any way of setting the watch, you probably have a "lever-set" movement, though it's possible you might also have a "pin-set" movement. Do you see a little button you can push in, either at 1-2:00 or 10-11:00 on the watch case? If you, you have a pin set watch. Push and hold that little button in while you twist the winding crown, and that will let you set the time. End of problem.

Setting the time on a lever-set watch is a bit more complicated and will require taking off the front bezel of your pocket watch--the metal ring that holds the watch crystal in place. Pocket watch cases of this time are usually made in 3 pieces: the bezel, the main case body, and the back. The procedure used to remove your bezel depends on the type of watch case you have.

Take a close look at the front of your pocket watch. Do you see any hinges at the bottom (that is, below 6:00 and where the bezel meets the main case body)? I suspect that you won't, as double-hinged cases are usually associated with an older style of pocket watch, but it's worth checking. If you do see little hinges for the FRONT (it's more likely that the back will be hinged), then look for a little lip on the bezel that's used to pry open the front. Pull on that to open the case.

If you don't see hinges, which is what I expect, your front bezel unscrews. You can try to do this with your bare hands, but it's a lot easier if you have a bit of "gripping" rubber so your hands don't slip so badly. I have a small rectangle of shelf non-slip stuff that works perfectly for this. Turn the bezel counterclockwise. It may resist a little bit at first due to accumulated dirt, but then it should easily screw off.

Once you have the bezel away from the face, look closely at about 2:00 on the watch dial. Just at the edge of the dial, you should see a little lever or button. GENTLY pull this away from the watch face until it stops. Now, when you turn the winding crown, you should be able to set the time. Once the time is set, gently push the lever back to its prior position. Now, you should be able to wind the watch without changing the time.

Be very careful when screwing the bezel back onto the watch body. These parts typically have very fine threads, and it's easy to cross-thread the pieces. Don't force the two pieces together; once the threads catch properly, the front bezel will screw on easily without resistance.

An older style of pocket watch required the use of a little key to set the time from the back of the pocket watch movement. However, these watches were also wound by the same key, so the fact that you're able to wind this watch with a crown suggests to me that your watch doesn't use this system.

Honeywell Old T874D1512 dual heat/cool thermostat


I think I understand what you are saying....First, that switch marked On and Auto, is to control the blower fan only. So when you switch that to On, it turns on the blower, but not the actual heat. It sounds more like a problem at the furnace then at the thermostat.
