Venmar EA 1500 won't run in Normal mode

I've installed a Venmar EA 1500 air exchanger, in place of an older Venmar exchanger, and reused the existing ductwork. The unit will run in recirculation mode (no air exchange), but in normal mode the unit continuously starts and stops in about 2 second intervals. I've checked the control wiring and all seams to be correct. Any thoughts?

When set in smart mode it runs continuously and the core ices up this results in the filter not being able to be removed. water then runs all over the floor. This also happens in normal mode Very li


Ice builds up for two basic reasons:
  1. Impeded air flow. This causes the dehumidifier to run constantly as the humistat never reaches it setpoint as there is limited or no airflow over the coils. Even with a filter, the cooling coils can become clogged and render airflow restricted or non-existent. Check and correct as necessary.
  2. A low refrigerant charge. Systems can leak over time and become low on charge. This causes extended period of running and the resultant freeze-up. If the coils and filter are clean, have the system checked for proper charge of refrigerant.

My LAD30NUL won't run continuously.


The bucket closes a switch when inserted. This prevents your dehumidifier from operating without the bucket in place. You will have to jump the switch to accomplish what you are intending to do

Dirty heat exchanger


the condenser (air intake) is blocked, most likely with dust, and the fan isn't passing enough air flow. either the fan is overworking and making noise or the compressor is overheating. if it can't cool down, the evaporator (cold coil) won't get cold enough to collect condensation. unplug the unit, take it outside, open the front, and hose the condenser down. if you can see light through it, it's ok. if not, spray some simple green degreaser on it and hose it down again after about 5 minutes. if you have a stiff bristled brush, use that, too.

Put empty bucket in,it runs for minute,then shuts off. need a switch that won't shut off. Where could I find one my zip code is 44451.


The switch may not be the problem. However, a dirty or clogged air intake filter or the humidity extraction level set to high could be.

Turn the unit OFF & unplug it.
Remove and clean the air intake filter thoroughly. Be sure the filter is completely dry, before reinstalling. Never operate the unit without the filter in place.

After the filter is dry, reinstall it, plug the unit and turn it ON. Lower the humidity extraction level to 35%. If you have an analog unit (No LED screen) set the humidity extraction knob on Maximum.

And finally, be sure that the water collection bucket is installed properly and is not vibrating loose when the unit runs. It should fit squarely into it's holder, making contact with the bucket safety removal switch on the back wall of the bucket holder. When installed properly, it should not tilt down at the bottom of the bucket.

All of the above should solve the problem and you won't need to purchase a new switch. But, in the unlikely event, that you will have to. You will need to furnish the Brand Name of the unit and the Correct Model Number. As, they are not all the same.

Deumidifier is running but the bucket won't collect any water. I've set the desired humidity level to 35% (ambient humdity is 75%) as well as cleaned the filter


There are 5 basic, yet solvable reason for what you described. The first 2, you have already covered. If our unit is operating in a basement, pay close attention to # 5.

1. The humidity extraction level is set to HIGH. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

5. Ambient air temperature at floor level is between 40 - 60 degrees.
dehumidifiers do not work well between those temperatures
(Unless, you have a Low Temp Unit). This applies mainly to
where the air temperature at floor level is colder than at shoulder
level
in basement applications. Raising the unit up off the floor,
onto a sturdy table, counter top, etc, that can handle the weight
of the unit, plus a full tank of water, will usually resolve this
problem.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

I hope this was of help to you. Thanks for choosing FixYa.

Dehumid....ad70usso....runs all the time auto settings don't seem to working collects fine ..but won't turn off when air is dry thanks


There are 4 basic, but solvable reason for what you described. Please pay particular attention to numbers 1 & 2. Also, keep in mind, basements stay moister longer than upper rooms.

1. The humidity extraction level is set to HIGH. Lower it to 32-35% and disable the auto mode.

2. Air intake filter is dirty or clogged. Turn unit OFF, & Unplug the
Unit, before removing to inspect & clean it, if necessary. If washed,
allow filter to completely dry before reinstalling. DO NOT operate
the unit without the filter.

3. Obstructed air flow. Maintain a minimum of 12 to 18" of clear air
space around the entire unit.

4. Cooling coils are dirty and need to be cleaned. Use warm water & dish washing liquid to
clean the coils. Rinse and wipe dry. Apply a light coating of WD40 to the coils.

If none of the above solves the problem, it may be a case of the compressor needs to be recharged with refrigerant gas or that the humidity condenser sensor has failed. These things usually occur in units that are 5 years old or older. It's rare in a unit younger than that. But, it can happen.

When the humidity set point is reached, the compressor shuts off but the fan continues to run. Is this normal?


Chucke - Depending on which mode you're operating the unit in (Continual Mode), yes that is normal.The fan continues to run in an effort to recirculate the air. If it senses a rise in humidity above the level you have it set on, the compressor will turn and remove that humidity.

Hope this helped you.

My dehumidfier won't shut off. I check everything out and it's good but it just won't shut off it keep running.


It may be, that you have it running in continuous mode, rather than timed mode. Also, most dehumidifiers fans will run almost continually, to keep the air moving, so the humidity sensor can pickup and increase in humidity, if there is one.

If the above doesn't seem to be the problem with your unit, turn The Master ON/OFF Switch to OFF and unplug the unit for 12-15 minutes. This will give the electronics time to reset themselves, if necessary.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

Furnace/air cond. blower motor is smoking


I recently installed a horizontal gas furnace. All the electrical and gas supply was done correctly for sure, but upon the trial run, some smoke was coming out the supply lines into the house. I used some flex duct tape to seal all ductwork for air leaks. I also used some inside the first box coming off the heat exchangers to seal the inside of the box for leaks. Could the tape be burning because its to close to the heat exchangers and smoking or is it because its because its brand new and the heat exchanges have to burn a while? Please help

Dehumidifier automatic on and off function not working


Unless you live in a dry environment or place the unit in a hermetically sealed room, it probably will not turn off. As the air dries within the room, more moisture comes in with the air. As long as the air outside of the room is more humid than the room this will be true.
