I recently encountered some problems with my Coal Trol unit and my convection blower.
It started about 2 weeks ago. I have only has the unit for 9 months and 4 of them been summer and it was not run.
What happened was the motor seized and would get extremely hot to the touch, also a strong burning smell throughout the house.
What i cant seem to understand is why I was supplied with a coal trol that has a 3 amp max(this is labeled on the black box that all my motors plug into)
for the convection fan plug ,it also is making my convection fan run at multi-speeds. And the convection fan (Dayton 5c091c supplied from keystoker) which is a 4 amp motor and is also 1 speed motor
On Friday I had to go to my dealer and get a new convection fan (The windings were fried, burning smell and seized). They replaced it with a (Dayton) 1xjx8 it is also a 1 speed motor and 4.9 amps.
I was told by my keystoker dealer I was the 3rd convection fan problem with the Coal trol. He also told me he never replaced one on a fan limit switch.
To sum it up,
Someone made a mistake and I had to shell out $70 for a fan limit and not to count the added aggravation. Keystoker totally dismisses it and told me they sell thousands and never had a problem. Automation Correct sent me a updated thermostat but i can not see that fixing this issue. I should be reimbursed for the switch plus the time i was without heat. I didn’t spend $3000 for my Koker to have problems in less then 1 year of operation. I do understand things happen but stand behind your product and fix the issue and inform the customers who have purchased these so it can be fixed and avoided.
What I also want to know is how you can control a 1 speed motor to go different speeds? Voltage? Amperage ? Ohms ? Hz? Or is it impossible with out eventually frying the motor. When i get a voltage reading from my unit it is only 60 volts. Half of what is required to run my fan. But I get 115 volts form my combustion blower. I am really disgusted confused and want some answers!
