Remove the top section of the heater. You will notice at the lower Right Hand of the back of the heater a small black plastic bulb with a yellow wire. This is the sensor fot the unit. Take a microwavable bean bag and heat it up in the microwave to a temperature a little greater than your body temperature. Place the bag on the bulb and then try and start the heater. If the heater does not start, your sensor is working but may need to be relocated. If it still runs, call a technician.

When in the heat mode the system will start and rune only a few seconds then stop. After a short pause the system will re-start and run ubitl the set temp is reached

Bruce, what you may be hearing is a short cycling of the fan and not a short cycling of the system. The fact that you indicate it only does it once per cycle kinda suggest that. If the ENTIRE unit was shutting down, it could indicate an adjustment in the 'heat anticipation' circuit on the thermostat sub-base was required. The heat anticipator is an adjustible resistor on non-digital thermostats that warm the spring that rotates the mercury bulb to cause it to shut off just a little bit before attaining setpoint...thus 'anticipating' the shut down temp and not 'overshooting' the setpoint.

Too low of a setting and the system will short cycle, too high of a setting and the system will overshoot the setpoint. The typical setting is .4 amp which is where the majority of sub-bases are set at from the factory.

My domestic rv ac unit reaches the temp setpoint and the compressor shuts off but not the fan, it just keeps on running. Is this normal or should the fan shut off also?

Set fan setting to auto and not high or low setting. Fan will cycle with compressor after setting set to auto or " au" if a digital thermostat.

Not working

There is a thermostat on the unit. it is probably set too low.
So the heater quickly hits the low temperature and shuts the heat off, then when the temp drop it will come back on.

Sounds like thermostat is failing. There is a factory set resistor that helps the thermostat keep a 2 degree accuracy. Second possibility is that you have a fan or direct airflow from the cooling system, being devirted, that is allowing the cool air hit the thermostat on the wall.

Hi, I have a Dayton 3ug73 heater. The heater will not shut down after the initial heat requirement is met. I have the thermostat set on low but it continues to heat. I shut the power off to it to keep...

It sounds to me like your thermostat may be bad. I would check power incoming to t-stat then turn temp. setting up and down to see if it is switching on and off. If not then replace. If it does then I would check all wiring to gas valve and if power is shutting off to valve but burner continues then replace gas valve. Thank you.

Temp set at 68 degrees but goes to 66 and the heat pump never shuts down has an electric aux

Depending on the outside temp. your heat pump might not keep up with the demand. It is not economical to run your heat pump in temperatures at or below freezing. Doing so could cause compressor failure and these are not cheap to replace. I would be running the aux. electric in low temps.

Outdoor A/C unit fan

If the fan and compressor are shutting off. its possible its cycling on a low pressure switch. probably low on freon.

or you have a low ambient kit to keep pressures up during low outdoor temps while ac is running just the fan will shut off, however thats not a typical thing to have a residential system

TB8220U Commercial Thermostat keeps running when temp is right

the temp coming out of the vent should be 20 to 25 deg more then room temp and if AUX heat kicks in the temp should be even more.
