You probably have a bad breaker.

Check to see if you have 220 volts coming into the breaker. (while the breaker is in the ON position) and check to see if there is 220V coming out of the breaker. If no, then you have a bad breaker.

If you do, let us know and we can help you diagnose from there.

Why won't it start?


It should automatically restart.....BUT what happened is that when you unplugged it, you cut off the blower at the same time you cut off the heat element(s). The way it is supposed to work, is the thermostat cuts power off to the elements and the fan continus to run for a per-determined amount of time to remove al the heat from the elements. Then another 'fan control switch' shuts off the fan once the 'residual' heat is removed from the heater. Without that 'cool down' cycle, the hot element had enough 'residual' heat in it to trip off the 'thermal overload' in the circuit. The 'thermal overload'... or...'hi limit'...or...'hi temperature control' is resposible for shutting power off to the element(s) in the event that the blower fails.

Check the thermostat and make sure the fan switch is set on "Auto". If it is set on "ON" the blower will run constantly.

Weathermaker 9300ts wont turn on ac compressor. The insind blower is working The fuses at outside unit is good and yes power is there. the heater works. no flasing lights


How do you know power is at the outdoor unit? Did you check it with a meter? Check your breaker. If there's power at the outdoor unit, then shut the power and test your contacter. If the contacter has supply power then check the low voltage (24-28 volts) that operates the contacter, and if none check the low pressure cut-out,high pressure cut-out and make sure the thermostat is calling for cool. All ok so far, then test your capacitor. I forgot to mention to check for loose, broken, and disconnected wires.

Goodman gmh95. The fan runs, cuts out, starts, cuts out as it nears set temperature.


If that's a variable speed motor(?), I've seen them do some strange things. Not that scenario that you have though. If it's under a parts warranty, have your tech start changing some things out, motor, control board to start with. It appears that your thermostat may be loosing contact? I know he bypassed it but how? And was the bypass for a few minutes or so? Or that you're issue seems to occur after 5-15 mins of operation, and that just happens to be a long enough run time to closely reach the set temp. at the thermostat. And that getting close has nothing to do with it, but the 15 mins of runtime is a better description. So have your tech over, warn them it may take 2 hrs, and pay him to hang around a catch it acting up. And set your tstat to allow it to get cold inside so it will run a lot when he gets there. Also, when it acts up, turn your fans' AUTO/ON switch to on, and see if it qits acting up. Not sure what that will answer but it may help you tech, depending on how it's wired. Hope this helps!

Does the Kenmore Series 700 dryer use circuit breakers or a thermal fuse to shutoff the heating element?


All Kenmore Electric Dryers use a thermal cut-off or thermal cut-out, hi-limit thermostat, and a cycling thermostat apart from the motor centrifugal switch as parts of the heating circuit. The thermal cut-off/thermal cut-out and the hi-limit thermostat are located on the heater duct/element duct while the cycling thermostat is located on the blower housing.

The thermal cut-off/cut-out serves as a safety measure and blows open should the dryer overheats or should the hi-limit thermostat fails to cut off power to the heating element. Check the continuity of the thermal cut-off/cut-out and if open, replace it including the hi-limit thermostat.

The problem is likely in the thermal cut-off (cut-out) and the high-limit thermostat located on the heating element housing. Verify this condition by bypassing the said components. Disconnect power then remove the rear access panel to access the thermal cut-off (cut-out) and the high-limit thermostat. Disconnect the wires of each component then connect them together and insulate it properly. Reconnect power then start the dryer. The problem is indeed in the thermal cut-off (cut-out) and the high-limit thermostat if the dryer heats up. Replace both parts and it should solve the problem. It is an easy and cheap repair to make.

The
thermal cut-off (cut-out) and high-limit thermostat are sold as a kit with part number 279816 and costs about $30.

In case the dryer still doesn't heat up with the
thermal cut-off (cut-out) and high-limit thermostat bypassed, bypass the cycling thermostat then replace it if the dryer heats up. Check the heating element for broken coils if the dryer still doesn't heat up with the three components mentioned above bypassed.

AC WORKS FINE HEAT COMES ON BUT WHEN TEMP IS REACHED FAN NEVER GOES OFF AND TROUBLE WITH HEAT COMING BACK ON


When temp reached to thermostat level heatewr only will cut off not the blower. And secondly all thermostat at heat stage will cut off at the end of +2 degree and cut in starting of -2 degree.

E.g; If you keep 30 degree heat it will cut off at 32 and cut in 28 degree.

The blower on the cooler stays on, won't cut out.


Possible that the thermostat is not working, ry reducing the control down to see if the cut off takes place.
It there is no action, shut offfor 8 hours and check witha lower settings. If the unit goes on , then you have to check the thermostat and control for fault.

It's obviously on the 12voltDC circuit of the AC unit. Sounds like thermostat, or a relay in control box is faulty or bad connection. If you remove cover on ceiling assy., you should be able to hear it in the control box. There should be a model number on the ceiling assy., get back to me with that number and I can better pinpoint which relay. Also, try moving all thermostat buttons and temperature controls back and forth quickly to see if it may clean off a dirty circuit in thermostat as well. Make sure your AC hydro breaker is off when working with ceiling assy. just to be safe.
