Airhandler- the themostat is on auto/I understand cool,heat.emerg heat,The (G) terminal-then why heat mode or,emer heat fan blows?Only when i switch to cool mode the handler still want start up blowing...


the fan fill come on with the sequencer (stack switch you call it) it will also come on with the fan relay. on some goodmans the fan relay is the black box on the circuit board. use a jumper to jump red to green, this should bring the fan on sounds like you could have a broken green wire, try using a different wire instead of green

Make sure the spa is not on sleep mode "SLP" or economy mode "ECO". Without knowing what type of spa you have it's hard to diagnose but it's possible your pressure sensor or high limit sensor it temporarily out of balance. If that's the case, it will resolve itself. If the problem persists you have a faulty faulty pressure switch or sensor.

Dryer won't shut off.


Will the timer advance in the NO HEAT mode? If it does advance you would know it has something to do with the temp alright but if it don't advance in No Heat then the timer motor is bad in my opinion. And it can fail by more than one way. Open winding OR stripped motor gear.

Heating won't go off


Honeywell manuals are online for all its thermostats.
Google search your model number.
Model number is on back of thermostat.
Copy following link for Honeywell resources:
http://yourhome.honeywell.com/home/Applications/FindYourModelNumber.aspx
Honeywell manuals are detailed, but each pdf file can be word-searched.

1998 blazer heat works great but defrost doesnt, could there be a blocked hose and how do i check?the defrost at the front wont blow.


if you have heat and nothing blows on defrost then this is a mode door problem that is not changing from floor to vent to defrost mode.it could be the mode switch or the mode door not working.the mode door is on the air duct under the dash and you can manually move it when you disconnect the control with your hand it should move freely.some of these have a small motor that moves the door.and if you move the switch in different modes or better have someone move the switch while you see were the door is the one that is moving is the mode door.if it won`t move on defrost tap the motor and see if it starts to work.if it does then it will have to be replaced if not it could be a switch problem.

Spa won't heat unless in spa mode, and if it is in


On the automated valves there are tiny switches on one end or under the valve actuator. When you switch to the spa mode the suction valve should should move to fully block pool drains. The return valve should fully block the pipes to the pool returns and spa fountain. If one or both of these valves is not fully blocking the pipes to the pool then the tiny switch on that valve is in the wrong position or an operator is defective. The middle position of either of these switches turns the operator completely off so it cannot move. That is the position to avoid unless you want to operate it manually. One of the other switch positions caused the valve to move in one direction and the other switch positions causes the valve to move in the other direction. If you set the switches so when in the spa mode water is circulating only in the spa then you have the valves in the right position. Next, place the system into the pool mode. Both valves should move to the other position. If not then the valve operator that doesn't move has a problem. It could be the operator, the wiring, the control panel or a stuck valve in that order. All of this sounds complicated but once you know how the operators should act when you flip those tiny switches and how the valves should act when in the spa and the pool mode then getting the switches set right is simple. I hope this helps.

Jura c9 on out of box start up won't leave rinse cycle and enter heating mode. Checked rotary dial but it seems fine.


You need to be patient and keep pressing the rinse button. I took a few water tanks of rinsing before it clicked over to heating mode. The manual and DVD need to mention this!

Mistral mss15 aircon will not operate on heat setting , not sure if it is being set properly because cannot understand remote control symbols


My Mistral was working yesterday (on heat) now it won't. Just sits there as if warming up but actually blows out freezing air - on "sun" mode.
