Electric dryer - repair or replace?

[Max T.]

Got a call from my temple university rental property that was just purchased a few months ago, so not much experience with this particular property or tenants yet. He tells me that the dryer spins but doesn't heat up. He checks for lint blockages but there are none. I put him in touch with my appliance repair guy who is very good an fair but does charge a flat fee to just for his trip $65. So if he tells me it's not worth fixing I'll have his cost on top of the cost of a new dryer. Now I'm second guessing myself. Should I have just ordered a new dryer? Part of me is being lazy: I'm in the airport headed out of town for a week and didn't want to think about rushing to the property to install it as soon as I get back in town. The property cash flows about 400/month. A new dryer would kill a whole month, while a repair would probably eat half.
