Gas emergency heat pump comes on with chemical odor


Answers :

If the emergency heat doesn't come on very often, it will burn off debris that has collected on the heat exchanger causing the smell. Also, check that there aren't any chemicals that are being stored around the unit that would put out fumes that can be drawn into the system and when heated, cause the odor.

We just started getting a chemical odor when our heat pump comes on,I was worried that it could be harmful so I called the fire dept. They came out and said since there was no gas to the house they couldn't test for gases and that freon couldn't hurt you, Is that true if we have a leak? What could be wrong?


You may have a small refrigerant leak in the exchanger coil in the furnace. \015\012\015\012You might want to have a heating/cooling tech check the charge on your unit to see if it has leaked. Then a dye test can confirm if there is a ... Goodman CLQ36AR49 Air Conditioner

Amana heat pump emergency heat comes on but blower will not start. The call for heat comes in and the heating element(s) glow red for a few seconds and then there is a "click" and the heating strips de-energize. The blower fan motor doesn't come on, however the squirrel cage fan spins freely. The heat pump stopped working several years ago, but I just used the emergency heat option for heating solution. The squirrel cage fan motor was replaced about 3-4 years ago.

I have a Rheem A/C Heat Pump split with gas backup. The gas unit is mounted in the air flow directly before the A/C HP coil. Should the gas unit be wired as stage two heat, or is it OK to wire it as just aux/EM heat? There is no other heating unit. What is the difference between stage two and aux? Please note that the aux gas heat cannot come on if the heat pump is running or it may hurt the heat pump due to the gas heat units location.


Stage 2 is okay as long as there is a fossil-fuel kit accessory wired in the field control wiring. EM heat would only allow gas furnace operation if the thermostat is set for EMER HT mode.......this is not ideal and not recommended. Dual-Fuel applic ... Air Conditioners

I have a heat pump system with gas as auxillary heat. What outside temperature should I switch my thermostat to "Emerg Heat" to run only gas? I also have a dial that appears to be some sort of temperature control on the lines that run outside the house to the compressor unit (currently set at approx 32). Is this for defrost control or does it tell the heat pump to shut down when the outside air gets below where this dial is set and then use only gas heat?


The dial thing you are talking about is a low ambient control that will not let the heat pump run below the set temperature should be set between 32 and 40 degrees farenheit. The heat pump is not effiecent below 32 degrees as I would reccomend only r ... Air Conditioners

I have an AR32-1 with an emergency heat switch on the thermostat. The heat pump runs and runs and runs and blows cold air when it's freezing outside. If I turn on the 'emergency heat', nothing happens. We do have three 220V breakers in the panel box. One is labeled 'heat pump', the other two are labeled 'furnace'. What could be wrong that the 'emergency heat' does not work?

I am trouble shooting a Bryant Hi-bred system that uses an air cooled heat pump with high efficiency gas furnace for backup and low ambient operation. How does the system decide whether to use the air cooled heat pump or the gas fired high efficiency furnace. It appears to be outdoor air temperature related, but I can't find the setpoint for it. The main zone Bryant thermostat appears to control the system, but it doesn't always bring the backup heat if the heat pump doesn't function.

Dear FixYa Experts, I am a new home owner. I have a Kenmore Air Conditioner (heat pump?, see more details below) with Lincoln Gas Furnace. According to the former owner, the heating system will start heat pump first when the temperature is above -15C and then turn on the gas furnace when the temperature drops below -15C. Recently, when I turn on the heating system, only the gas furnace was always running but not the Kenmore air conditioner. And our average temperature was always above +5C for
