Question about Heating & Cooling

1 Answer

Eheat will not come on

The heat pump works, but eheat does not. This system worked earlier in the season, but has been off a couple weeks. When I tried it today, the theromstat said 'clean filter aux heat,' so I did that;I also replaced intake filters then pushed the reset filter button. Nothing happened. I also turned off the power switch to the unit for a few minutes. Still nothing. The only sound I hear is the thermostat control click to signal the change from heat to eheat. Is there anything else I can try before calling for service?

When resetting anything electronic, leave switched off for about 15 mins. The electronic boards store the memory of any failure or problem and switching off for only a few seconds or minutes will not reset the board. Turn off at the mains supply not the wall control.

If you are having trouble with the flue icing up on the air side, just remove the flex air hose from the back of the unit. It will now **** room air. When the weather conditions change you can hook the hose back up. As you can see the flue doesn't give much space for the air. As far as the front cover, I think you need to clean the circulating fan blowers as well as the screens.

Good luck,

SOURCE: Toyo Laser 56 EE2 message--no flame? valves open and clean filter

You might of got type 2 fuel oil. If it is a smaller tank sometimes the fueler doesn't clear the line before filling and you'll slug down some type2 which will snuff the flame.
Check to see if the filler kinked a line outside while filling.
Just an Idea...

SOURCE: Buzzing sound when aux heat comes on

Sounds like it could be a effiency function to warn you that the heat elements are on. Check your thermostat manual and see if you can turn this feature off. If this is not a feature then the thermostat may be wired wrong or something in the circuit may be trying to short out.

SOURCE: I have a Raypak 147CHL boiler used for our house's

Check to see if there is voltage going to the Hot Surface Ignitor when you first try to fire it up. If you have voltage but it fails to glow, the hot surface ignitor has failed and will need to be replaced.
Also ensure you have proper flow through your boiler......make sure you have water flowing through the boiler and, if there is a flow switch, check the voltage across the two terminals of the switch......check each to ground for voltage. If you have voltage, then check the voltage reading across the two terminals themselves, you should read 0 volts across the terminals (indicating the switch is closed).
Hot surface ignitors are "wear-n-tear" items and should be the first place to check.
I hope you find this information to be very helpful to you moving forward.
Please let us know if you need further help. :-)

Testimonial: "Hi Laddybug68, thanks for your infor. My system is nearly 10 yrs old & I haven't replaced the ignitor before. I've replaced the ignitor which was a Norton mini 401 mounted along side a flme sensor. I also replaced the Igniter control board /box which was a RAM-H4M7-01 and the boiler is working. Thank you very much. Regards Afanco ( Melbourne, Australia)"

SOURCE: A/C won't kick on w/

Okay it seems that for some reason the battery change scrambled the brain of the t-stat... that happens...
To fix it you will now have to go into the "Installer Menu" and reset the paramenters of the t-stat.
If you have the Installe brochure then you can look in there and then set the tistat for "heat/cool" and also to "auto fan" and then to "auto changeover" These should get you back to cooling again...
No big problem, just a small programming patient and if you do not have you book don't worry... you can look it up here...this tip tells you where and how to find any of the Honeywell t-stat manuals.

I have a hayward H200 series heater and th eheat exchanger is leaking. I have pulled the heat exchanger out and cant see anything visible it is probably leaking inthe area covered by the fins. I have...

You need to buy the whole unit as these are pressed in place together. If you have a leak it is most likly due to chemical damage and goes further. So at the least you will need an exchanger. I will usually try to get people to go with a new heater if it is more than a couple of years old due to cost and hidden damage that can only come out after you install a new exchanger. Sorry for the bad news.

Instead of the heating element turning on the heat pump runs out side thermostate is not set on eheat

The heatpump is your 1st. stage heat, when you have a call for heat it will bring on the outdoor unit.
When the first stage heat can't heat the house and the indoor temperature drops 2° or 3° then 2nd. stage heat will kick in and maintain the house temperature at about 2° or 3° below the temperature setting.
If you outdoor unit fails or goes into defrost then emergency heat will kick in and keep the house at 2nd stage temperature approximately 2° or 3° below thermostat setting.
If you have an outdoor thermostat or balance point setting on outdoor board, it will shut the outdoor unit off at a certain set outdoor temperature and the 2nd stage heat will be primary heat for the house.

Carrier heat pump: aux heat does not seem to work

The unit is probably to small for theare you are trying to heat.

When the Aux HT light came on that meant the heat pump could not keep up with the demand for heat. (Probably due to extreme cold, or undersized unit.)

If yu have heat, then at least one heat strip is operating. If you have multiple heatstrips, one or more could be malfuncioning.

Or it could simpy be to cold/to small fr your area and not able to keep up.

How many square foot are you trying to heat?
What is the outside temp?
What is the inside temp?
What size unit (BTU output) do you have?

Carrier thermostat

I hate to say it but Ive had trouble with Carrier's Tstats doing similar improper things. Unfortunatly the only repair is going to be replacement of the whole tstat. I recommend Honeywell's FocusPRO or VisionPRO tstat. Ive yet to have one fail and they have a 5yr warranty if they ever do.
