My 2006 hot spring grandee spa won't heat.

Have you checked the heating element? Is the spa showing it is heating up but does not? That would indicate a bad temp sensor.

Heat pump?

There could be several issues at work here.

  • First, is the heat indicator light showing on the topside?
  • Is the pump running but temp is not rising?
  • Any error codes displayed on the topside panel?

The drop in water temperature could be caused by a faulty temp sensor or faulty high limit sensor.

Check those items out and see what you come up with.

My AC 1200BTU work in heating 5min. and than stopped

Check temp setting and also room sensor. Setting must be minimum 3 degree more than room temp. Check continuity for sensor. If open replace it. Check coil , air filter and heater element are cleaned.
If high amps, replace heating element. Thanks.

When I turn on ac, temp in room comes down, temp on machine reads 95F could problem be exhaust hose has some tears?

The temp sensor is located on the upper rear just behind the air filter. Slide the filter out and give it a cleaning. Look for a small wire visible. Inspect the temp sensor; it gets dusty.

If the hose was leaking you would feel the heat in the room.

Carrier furnace will not heat house. Turned circuit breaker off and on again and it will kick heat on but only heats to move temp up 2 degrees. LED light is continuously on. All the manual says is 24 vac...

Sounds like it will not stay on long enough.I would try cleaning the flame rod/sensor.A steel pin next to the pilot or near the last burner to the left.Has a wire attached to it polish it with fine grit sand paper.

Dryer wont heat and check filter light is on but filter in dryer is clean?

This could be caused by a venting restriction. These dryers have sensors built in to check airflow temp differences. Take the vent off the dryer and run it and see if it heats. If it does then you know the problem is with your venting. You will need to either clear the vent or replace it.

Hope this helps _MJ_

See description to the left

Ford 1989 F 150
Is this 4.9 L (6) cyl. ?
Truck runs until hot then quits. Cools down then runs again.

You can get error codes. Many auto parts stores will have free loaner meters to read them.

It could be the hall effect sensor in the distributor. You need to test for injector pulse and if you don't have a pulse, the hall effect sensor will be suspect. This sensor checks for crankshaft position in earlier models instead of a cranks position sensor. The TFI module plugs in near it.
Use a noid light for Ford plugged into an injector and crank the engine to see if it lights.

No heat and filter care light constantly lit

Have you cleaned the filter and the filter compartment?

Try that, then unflug it for about 10 min, then plug it up and try it again.

This will reset some units with an auto reset high temp limit switch.

What happens when a filter gets dirty/clogged is that not enough air is blowing accross the heating device. This lets it get to hot and it will shut off for safety to prevent fires.

If everything is clean and after pluging it back up it still gives you that code you may have a bad sensor.
